The culture of Perky Pat cannot tolerate the heretical concept of their toy becoming married, of changing. This runs a parallel with how societies sometimes become more inflexible as they cling to an artifact of a past that may never have been.
Those halcyon days are scrubbed clean of their impurities and real reality just can't stand up to it. Add to it that the regular supply drops from the Martians mean that the adults really have very little to do. The more leisure a society has, the more likely it is to come up with structure to fill up the time and effort they would have normally expended on ensuring living conditions.
Humans are very prone to organizing into groups that band together against outsiders. The two enclaves are essentially the same other than different doll sets. While not really stated in the story, it's likely that the same conditions that reduced the enclaves to surviving on Martial supply drops have also removed many of the social conditions people use to set themselves apart.
Everyone has standard housing and standard food with the Perky Pat dollhouses and accessories being the only real way to distinguish oneself. The couple who win the competition have been tainted by their association with the other conclave and are no longer considered part of their home.
PKD is often prone to re-using a short story as a chapter in a book, or pulling a chapter of a book out and publishing it as a short story. Since he often re-used themes between his works, comparing them can shed light. Perky Pat is a side plotline from the Three Stigmata of Palmer Eldritch which goes into more detail about how Perky Pat layouts are used.
Of course, by reading that you may replace one open question about PKD's work with a dozen. In the book, perky pat layouts are used for a quite literal form of escapism, by taking psychoactive drugs and concentrating on your layout, you can cause your hallucination to take the form of your layout and you take on the role of Perky Pat.
Questions Tags Users Badges Unanswered. What is the story or metaphor behind Perky Pat? I read Perky Pat a few days ago and it doesn't make sense to me. Summary from Internet updated: If something in a Philip K. Dick story appears to have no sense, it is only because you have misread it. Escapism Faced with harsh realities, the adults are too rigid to deal with the ruined world outside.
Rigid social structure Culture is a very rigid and yet undefined field. Cliques Humans are very prone to organizing into groups that band together against outsiders. This makes it much clearer for me. You said, "Everyone has standard housing and standard food with the Perky Pat dollhouses and accessories being the only real way to distinguish oneself.
It can also be read as a critical of materialism: Studies have documented the negative effects of mental imagery on perception also known as the Perky effect in younger adults, but imagery-interference effects in older adults have never been assessed. Two experiments examined this issue directly. Processes underlying age-related differences in imagery-interference effects are discussed and implications of these results for changes in cognitive performance in older adults are considered.
There is an extensive research literature substantiating age related changes in cognitive abilities. Older adults those 60 years and older show poorer performance relative to younger adults between 20 and 40 years on a wide variety of tasks, most notably those involving divided attention, 1 working memory, 2 — 4 explicit recall, 5 , 6 episodic memory, 7 performance intelligence e.
Aging may also adversely affect an array of imagery abilities including image generation, 10 — 12 image manipulation, 12 — 15 , 16 image maintenance 17 and mental rotation. Numerous studies have been directed toward delineating the psychological and neurological processes through which aging impairs mental imagery. These studies have provided evidence that age-related deterioration in sensorimotor function, processing speed, working memory, and executive function mediate the decline in mental imagery ability observed in the older population see Ref.
A component of mental imagery that has not previously been examined in the context of aging is the impact of mental imagery on perception; that is the purpose of the present investigation. This comparison is of both theoretical and practical interest as age-related differences have been reported for the ability to use mental images e.
The critical measure in this report concerns imagery-induced reduction of perceptual functions--the Perky effect. In her pioneering studies, Perky discovered that participants could not always distinguish their visual mental images from visual percepts; they were unable to detect dim yet above threshold pictures while mentally imagining common objects. This suggests that limitations in attentional capacity cannot by themselves explain imagery-perception interference effects.
Although there have been a number of studies demonstrating a Perky effect among college students, 22 — 27 this effect has not been examined in older participants. The purpose of the present study was to determine whether a Perky effect occurs in older adults as it does in younger adults, with age-related imagery deficits examined by comparing performance across perceptual and imagery tasks in older and younger participants.
We compared the effects of imagery on perception using two perceptual tasks. Experiment 1 examined the effect of visual imagery on visual acuity judgments while Experiment 2 used a detection task. On the basis of the literature, we hypothesized that older participants would produce significantly weaker Perky effects than the younger participants indicating an age-related deficit in their imagery ability.
In Experiment 1, we used methods that have reliably produced a Perky effect in younger participants, 29 , 30 but tested both young and older adults. Our participants generated and maintained simple images while performance was measured on a low level perceptual task, vernier acuity. Craver-Lemley and Reeves discovered a Perky effect--a decline in accuracy for judging vernier acuity targets--when college-age participants imagined a variety of patterns e. In Experiment 1 we elected to use simple line images since it has been demonstrated that the elderly have more difficulty manipulating complex than simple images: Thus, if the Perky effect is negligible or nonexistent under these conditions we will have provided compelling evidence that elderly participants do in fact have diminished imagery abilities.
Alternatively, if elderly participants produce Perky effects of a magnitude comparable to that of younger participants, then we can conclude that aging does not affect all components of imagery equally e. Two groups of volunteers were tested in this study: Both groups received payment for participating. All participants reported that they had normal or corrected-to-normal vision and were in good health. Participants provided self-reports indicating that they were not on medications that might impair their cognitive performance.
The older adults were living at home and traveled to the laboratory to be tested. They were recruited through the Penn State College of Medicine, and had previously served as controls in unrelated cognitive studies.
Stimuli were presented binocularly using a Gerbrands two-field tachistoscope Model GF7. The fields were 58 cm from the eyes. There were two dots placed 5. A relative intensity of 90 was set on the series Lamp Drive circuit. The test field was used to present the vernier acuity targets. The bottom line was equally often offset to the left or to the right in relation to the top line.
For each trial, participants were to report whether the bottom line was offset to the left or the right in relation to the top line. There were 10 different offsets that were presented in random order and used equally often; the range of offsets was between 4. There were two conditions. In the imagery condition participants were asked to evoke a mental image of four black vertical lines VL Figure 1b.
The VL image was to be projected within the fixation region and maintained concurrent with the target.
Participants were shown a sketch of four black vertical lines and were asked to center their image between the two points in the fixation field. Participants were individually seated in front of the tachistoscope and informed that we would be measuring acuity under two conditions: On some trials they would be asked to evoke an image of four black vertical lines VL , while for other trials they would just be asked to make the acuity judgments without an image NI.
They were instructed to initiate the trials themselves, after they had fixated and after in VL forming an image. The duration of stimulus presentation was determined individually for each participant during an initial practice period of about 15 minutes. Mean stimulus duration for the college students was 9. Imagery VL and no-imagery NI instructions were randomized and participants received 50 trials in each of the two intermixed conditions.
Participants were run individually and the experiment lasted about 35 minutes. The Experimenters in both experiments were undergraduate assistants with no knowledge of the predicted outcome of the studies. The stimulus cards in Experiments 1 and 2 were placed into the tachistoscope so that the Experimenter could not see what was on the card; therefore the Experimenter was unaware as to whether the participant had made a correct or incorrect response until after each trial was over.
Mean acuity performance with and without mental imagery, Experiment 1. The error bars were created using standard error. The accuracy rate of older adults was lower than that of college students in the NI condition, but higher than that of college students in the VL condition.
Young and elderly participants maintained mental images while making vernier acuity judgments. As expected, while the younger participants replicated previous research on the Perky effect, showing reduced accuracy under imagery, elderly participants showed comparable performance in the imagery and control conditions.
The results of this study lend support to reports of age-related performance decrements for image generation and maintenance tasks. Experiment 1 revealed that imagery produced interference for an acuity task in younger but not elderly participants.
Since an absence of a Perky effect in the elderly has not been previously reported, it was of interest to determine whether we could replicate this finding with a different perceptual task that also occurs early in visual processing. Experiment 2 used a design similar to Craver-Lemley and Arterberry Ref.
Participants were asked to project an image into a specified location in the fixation field of a tachistoscope and at the end of a given trial to report whether or not a target had been presented. It was expected that in the present experiment younger participants would replicate the patterns obtained by Craver-Lemley and Arterberry while elderly participants would--as in Experiment fail to demonstrate a Perky effect.
Ten Elizabethtown College students mean age The college students were enrolled in an introductory psychology course and received course credit for their participation. The older participants were recruited through the Penn State College of Medicine and had previously served as controls in an unrelated cognitive study e. All older participants were in good health and living unassisted at home. They were not on any medications that might impact their performance, and were paid for participating in the study.
None of the volunteers, younger or older, had participated in an imagery experiment before. All participants had normal or corrected-to-normal vision.
Stimuli were presented in the same tachistoscope as in Experiment 1. The stimuli were identical to those described in reference 23 , Experiment 5. Thus, a nine cell display was used for fixation Fig.
The display was Each cell measured 4. A fixation point was placed in the center of the central cell. The fixation field was presented continuously.
The test field was used to present the asterisk targets. Example of target in Experiment 2. Note for a given trial the target may appear as depicted in the center top cell, in the bottom center cell, or not at all.
There were 40 target cards. Each of the There were also forty white blank cards. On imagery trials, participants were instructed to generate an image of a gray vertical bar VB that would fill the three central cells of the fixation field Fig 3c. Participants were provided with a sketch of the requested image during the practice session. As in Experiment 1 there was also a no-image NI condition which served as a baseline control for the detection task.
For NI trials, participants simply executed the detection task. Participants were tested individually during sessions that lasted about 45 minutes. The mean stimulus duration for the college students was Participants were instructed to maintain central fixation throughout the experiment. The detection task was to report whether an asterisk had been presented in either of the two possible locations on each trial. Trials were run in two blocks of 80 for a total of trials.
Participants received a 10 minute break after the first block of trials. VB and NI trials were randomly intermixed. Participants were told at the beginning of a trial to either have no image or to imagine the gray vertical bar. For VB trials, participants signaled the Experimenter when they had projected their image.
Then the Experimenter presented either a blank or target card, after which participants reported whether or not a target had been presented. Feedback was not provided regarding performance on the detection task. As in Experiment 1, the results of Experiment 2 revealed that imagery did not produce a Perky effect in elderly participants.
Because a different perceptual task was used in Experiment 2 these results both replicate those of the first experiment and indicate that these patterns are not task-specific, but generalize across perceptual tasks that involve similar processes.
This finding provides additional support to age-related deficits in imagery. The aim of the present study was to determine whether or not there were differences in the magnitude of the Perky effect in young and elderly adults. Experiments 1 and 2 revealed that elderly individuals lose an effect of imagery that is well documented in younger adult populations.
For our older participants, performance on two simple visual tasks--acuity and detection--was not impacted by the presence of a concurrent mental image. As a result our older participants--unlike our younger participants--did not demonstrate a Perky effect. Thus, we have provided the first empirical evidence that the Perky effect does not occur for elderly individuals. Although our finding is new, it was replicated in two separate samples using two different perceptual tasks, and is in line with previous reports of reduction in imagery capabilities among elderly populations.
In fact, a focused comparison of effect size 32 confirmed that the magnitude of the Perky effect in younger participants did not differ across Experiments 1 and 2. An alternative that should be briefly addressed is whether or not the absence of a Perky effect among our older groups in Experiments 1 and 2 could be attributed to differences in stimulus durations rather than to the effects of aging on mental imagery ability.
The younger participants, showing a Perky effect, had much shorter stimulus durations. Perhaps older participants with shorter stimulus durations relative to their age group might exhibit the Perky effect as well.
However, this alternative may be discounted because only one of the older participants tested with a shorter stimulus duration below the median split demonstrated decreased accuracy for the imagery condition. Why do the elderly lose the Perky effect? First consider the imagery tasks. Both tasks required participants to generate and to maintain the same simple image throughout a series of trials. Although there are reports that the elderly are slower in tasks involving image generation, speed was not a factor in our experiment.
In fact, we were not concerned with how long it took our participants to generate their images; all participants had as much time as they required.. Escorts outcall perky breasts and biological perspectives. Hertzog C, Rypma B. There were 10 different offsets that perky adults presented in random order and used equally often; the range of offsets was between 4.
