One hundred forty-nine middle class individuals (69 males and 80 females), approximately 80% of whom were Caucasian, participated in the present study. The study was designed to test the hypothesis that individuals whose gender role and occupation did not match (i.e., feminine individuals in predominantly male occupations or masculine individuals in predominantly female occupations) would experience more gender role conflict than individuals whose gender role and occupation matched. The hypothesis was supported. A feminine gender role predicted higher gender role conflict in predominantly male occupations, and lower gender role conflict in predominantly female occupations than a masculine gender role. A masculine gender role predicted the lowest gender role conflict scores in predominantly male occupations, and the highest in predominantly female occupations. Furthermore, higher masculinity scores were related to greater gender role conflict for females than males in more predominantly male occupations.  相似文献

Two experiments investigated the effects of age and domain-specific experience on the speed and accuracy of visual inspection performance. In Experiment 1, young (M age = 26.5 years) and middle-aged (M age = 45.7 years) medical laboratory technologists (MTs) and matched novices were tested on a domain-specific version and on a domain-general version of a probe recognition task. Middle-aged subjects were slower than younger subjects on both versions, and MTs were more accurate but slower than controls on the domain-specific task. In Experiment 2, MTs and controls were tested on the same tasks under single-task and dual-task conditions. Middle-aged adults were slower and less accurate than young adults under dual-task conditions in the general version. For the domain-specific version, the response times and error data suggested that skilled performance is less demanding of age-limited general-purpose processing resources.  相似文献

Older adults commonly experience declines in episodic memory that affect their daily lives. The aim was to examine whether the acquired metacognitive awareness that comes with task experience, indexed by meta-retrospective memory (meta-RM)/meta-prospective memory (meta-PM), influences how older adults predict performance on later trials. Participants were 178 community-dwelling older adults. RM performance and predictions were measured using a multi-trial word-list learning task. Predictions and performance for PM were measured using a PM paradigm. Change in RM/PM performance and predictions over the trials/blocks were modelled using latent growth curve analyses. For RM, both predictions and performance increased with task experience. However, for PM, neither performance nor predictions changed with task experience. Hierarchical multiple regressions revealed that metacognitive awareness acquired during the RM and PM tasks influenced how older adults’ modified their predictions of subsequent task performance. Findings are consistent with [Toglia and Kirk’s (2000). Understanding awareness deficits following brain injury. NeuroRehabilitation, 15(1), 57–70] hypothesis that individuals compare ongoing performance to expectations based on metacognitive knowledge, such that a discrepancy between actual and expected performance may influence emergent awareness.  相似文献

The own‐age bias (OAB) in face recognition (more accurate recognition of own‐age than other‐age faces) is robust among young adults but not older adults. We investigated the OAB under two different task conditions. In Experiment 1 young and older adults (who reported more recent experience with own than other‐age faces) completed a match‐to‐sample task with young and older adult faces; only young adults showed an OAB. In Experiment 2 young and older adults completed an identity detection task in which we manipulated the identity strength of target and distracter identities by morphing each face with an average face in 20% steps. Accuracy increased with identity strength and facial age influenced older adults' (but not younger adults') strategy, but there was no evidence of an OAB. Collectively, these results suggest that the OAB depends on task demands and may be absent when searching for one identity.  相似文献

Neural correlates of age-related declines in prospective memory were studied by using event-related brain potentials (ERPs) in a task in which individuals formed and later realized simple intentions. The behavioral data revealed that prospective responding was less accurate and slower in older than in younger adults. The electrophysiological data revealed age-related differences in the amplitude of modulations of the ERPs associated with the encoding of intentions, the detection of cues, and disengagement from the ongoing activity. These findings support the hypothesis that age-related declines in prospective memory result from a reduction in the efficiency with which older adults encode intentions and detect cues.  相似文献

Quantitative estimates of the spatial discriminative capacities of the visual and kinaesthetic systems in adults and children were obtained. Intersensory integration was investigated by including spatial discriminations based on congruent visual plus kinaesthetic reafference. The psychophysical method of adjustment was used with simultaneous comparisons of a fixed and a variable stimulus. The subject's task was to estimate when the variable stimulus (ellipse) was identical to the standard one (circle), under one of three modality conditions: vision, kinaesthesis, and vision plus kinaesthesis. After a pilot study with adults, children (aged 8, 10, and 12 years) and adults were both tested. Subjects from each age group were randomly allocated to each of the three experimental conditions. Results show that the visual and kinaesthetic estimates of the 8- and 10-year-old subjects did not differ significantly, but the visual responses of the adults and 12 year olds were significantly more accurate than corresponding kinaesthetic estimates. Bisensory estimates were significantly more accurate than visual responses only for the 8- and 10-year-old age groups. Intramodal comparisons showed the kinaesthetic estimates of the 8, 10, and 12 year olds to be significantly more accurate than the corresponding adult performance. Adult visual estimates were significantly more accurate than those made by 8 year olds, but were not significantly different from the visual responses of 10 and 12 year olds. Estimates based on bisensory reafference did not differ from each other across the four age groups. It is concluded that modality adeptness and dominance are task dependent and empirically determined rather than being innate properties of sensory systems. The data indicate that intersensory differentiation rather than integration occurs with maturity.  相似文献

The present study examined the jumping to conclusions reasoning bias across the continuum of delusional ideation by investigating individuals with active delusions, delusion prone individuals, and non-delusion prone individuals. Neutral and highly self-referent probabilistic reasoning tasks were employed. Results indicated that individuals with delusions gathered significantly less information than delusion prone and non-delusion prone participants on both the neutral and self-referent tasks, (p<.001). Individuals with delusions made less accurate decisions than the delusion prone and non-delusion prone participants on both tasks (p<.001), yet were more confident about their decisions than were delusion prone and non-delusion prone participants on the self-referent task (p=.002). Those with delusions and those who were delusion prone reported higher confidence in their performance on the self-referent task than they did the neutral task (p=.02), indicating that high self-reference impacted information processing for individuals in both of these groups. The results are discussed in relation to previous research in the area of probabilistic reasoning and delusions.  相似文献

Five preliminary experiments on sighted individuals revealed marked overestimation on an object size-estimation task using a bimanual response. These experiments ruled out the possibility that overestimation was due to the mode of visual presentation (whether two-dimensional or three-dimensional), the input modality (visual or kinesthetic), or the influence of other visual cues. The main experiment then investigated whether these distortions are due to visual experience by using a variant of the same task to test 24 blind and 24 sighted control participants. Remarkably, the sighted control participants overestimated object size, on average, but the blind participants did not. A follow-up experiment demonstrated that visual memory was the primary influence causing the size over-estimations. We conclude that blind individuals are more accurate than sighted individuals in representing the size of familiar objects because they rely on manual representations, which are less influenced by visual experience than are visual memory representations.  相似文献

A number of studies have demonstrated regularities in how individuals select and perform single object manipulations, but little work has been concerned with the manipulation of multiple objects. To this end, the authors asked participants to stack a set of linearly spaced containers onto various goal locations. Our aim was to determine whether participants adopted specific strategies to complete this task. We focused on whether the distance between the objects, the goal location of the objects, or both, determined the classes of movement sequences that individuals used to perform the task. The results showed that some individuals tended to use one hand for lifting and releasing the containers whereas other individuals tended to use both hands for lifting and releasing the containers. Those participants who tended to use one hand varied which hand was used according to the goal location of the containers but not the distance between containers. The emergence of these individual differences provides a new basis for inferring psychologically distinct classes of motor behavior.  相似文献

The purpose of this study was to examine children's reported experiences of anger and their means of expressing anger in their interactions with high versus equal status individuals. Parents and teachers represented high status while siblings and peers represented equal status. Sixth grade children were asked to cite situations in which they experience anger in interaction with peers versus adults and to indicate their typical responses to these situations. We identified 13 categories of situations in which anger was experienced and 11 categories of response to these situations. Anger was experienced in interaction with both high and equal status provokers but of the situations that were identified as producing experiences of anger, nine were reported as occurring differentially in interaction with adults versus peers of the responses to the experience of anger, seven responses were cited differentially in interaction with peers versus adults. The typical responses to adult provoked anger were generally more passive than those to peer provoked anger. Girls more than boys indicated experiencing anger due to adult's task demands but tended to express less overt anger in their interactions with adults than did boys. These findings are consistent with the view that high status of the provoker servers only to inhibit the expression of anger but does not lessen the anger experience itself.  相似文献

Poor decision making during adolescence occurs most frequently when situations are emotionally charged. However, relatively few studies have measured the development of cognitive control in response to emotional stimuli in this population. This study used both affective (emotional faces) and non-affective (letter) stimuli in two different flanker tasks to assess the ability to ignore task-irrelevant but distracting information, in 25 adults and 25 adolescents. On the non-emotional (letter) flanker task, the presence of incongruent flanking letters increased the number of errors, and also slowed participants’ ability to identify a central letter. Adolescents committed more errors than adults, but there were no age-related differences for the reaction time interference effect in the letter condition. Post-hoc testing revealed that age-related differences on the task were driven by the younger adolescents (11-14 years); adults and older adolescents (15-17 years) were equally accurate in the letter condition. In contrast, on the emotional face flanker task, not only were adolescents less accurate than adults but they were also more distracted by task-irrelevant fearful faces as evidenced by greater reaction time interference effects. Our findings suggest that the ability to self-regulate in adolescents, as evidenced by the ability to suppress irrelevant information on a flanker task, is more difficult when stimuli are affective in nature. The ability to ignore irrelevant flankers appears to mature earlier for non-affective stimuli than for affective stimuli.  相似文献

Collaborative problem solving occurs in situations in which two or more individuals cooperate in appraising, representing, and solving a variety of cognitive tasks. Collaborative groups are the context for much everyday cognitive activity in adulthood. Collaboration has been explored as a means through which older adults may maintain high levels of performance, perhaps compensating for individual-level cognitive and neurological decline. This study explored the effects of collaboration (group size) and adult age on solving both fixed- and unrestricted-alternatives 20 Questions tasks. Younger (M=24.3 years) and older (M=67.9 years) adults were randomly assigned to one of three homogeneous group size conditions: individuals, dyads, and tetrads. Results indicated some dissociation between individual-level performance (poorer for older adults) and collaborative performance (better for older adults). For the fixed-alternatives task, older adults produced more of the relatively inefficient hypothesis-scanning questions than did younger adults. In contrast, older collaborative groups produced more of the efficient constraint-seeking questions than hhpothesis-scanning questions, and an amount equivalent to that of younger adults. Overall performance for the difficult unrestricted-alternatives task was less efficient for both younger and older adults. The roles of task type, group characteristics, and adult age are discussed.  相似文献

The present study tested the hypothesis that older adults establish a weaker task set than younger adults and therefore rely more on stimulus-triggered activation of task sets. This hypothesis predicts that older adults should have difficulty with task switches, especially when the stimuli-responses are associated with multiple, competing tasks. Weak task preparation, however, could actually benefit older adults when performing an unexpected task. The authors tested this prediction in Experiment 1 using a repeating AABB task sequence, with univalent and bivalent stimuli intermixed. On some univalent trials, participants received an unexpected task. Contrary to the authors' predictions, expectancy costs were not smaller for older adults. Similar findings were obtained in Experiments 2 and 3, in which the authors used a task-cueing paradigm to more strongly promote deliberate task preparation. The authors found no disproportionate age effects on switch costs but did find age effects on bivalence costs and mixing costs. The authors conclude that older adults do experience extra difficulty dealing with stimuli associated with 2 active tasks but found no evidence that the problem specifically stems from an increased reliance on bottom-up task activation rather than top-down task preparation.  相似文献

Prior experience with a cognitive task is often associated with higher performance on a second assessment, and these experience effects can complicate the interpretation of cognitive change. The current study was designed to investigate experience effects by obtaining measures of cognitive performance separated by days and by years. The analyses were based on data from 2017 adults with two longitudinal occasions, of whom 948 had also completed a third occasion, with each occasion consisting of three parallel versions of the tests on separate sessions. Change across short intervals was typically positive, and greater among older adults and adults with low levels of cognitive ability, whereas change over intervals of approximately three years was often negative, particularly at older ages. In contrast to the expectation that change over short intervals might be informative about change over longer intervals, relations between short-term change and long-term change were negative, as the individuals who gained the most with assessments separated by days tended to experience the greatest losses across assessments separated by years.  相似文献

Three experiments are reported which examined the relative effects of geometry and object-specific function on the comprehension of the spatial prepositions in and on. The first experiment manipulated the height of a located object on top of a pile of other objects in containers which were primarily containers of solids (e.g., a suitcase) or liquids (e.g., an aquarium). The association between located object and reference object was also varied (by using different types of objects as located objects). In was found to be more appropriate to describe the same object in containers of solids compared to containers of liquids, although no effects of located object association were found. Experiments 2 and 3 manipulated similar variables with supporting surfaces rather than containers, and examined the effects of functional control on the comprehension of on. The studies provide evidence for the importance of functional relations on the comprehension of on. In addition effects of located object association were found, but only when there was no clear evidence for the absence or presence of functional control. The results are discussed in relation to the differential effects of object knowledge on the comprehension of spatial prepositions.  相似文献

Using a joystick, adults (n = 39 males, 40 females in Experiment 1; n = 35 males, 40 females in Experiment 2; and n = 18 males, 18 females in Experiment 3) performed a computerized pursuit tracking task. Contrary to previously reported findings, the males were not more accurate than the females when performance was adjusted for prior perceptual-motor experience. Although no sex differences were found in a speeded tracking task, in an inverted tracking task the males exhibited a significant performance advantage; that advantage remained after several blocks of practice. Because participants' performance was adjusted statistically for prior perceptual-motor experience, the male advantage in inverted tracking was not related to experience. Rather, more proficient inverted tracking performance was associated with higher 3-dimensional mental rotations scores. In sum, sex differences in normal pursuit tracking may be better explained by differences in perceptual-motor experience. Inverted tracking, however, may depend on proficiency with spatial transformations.  相似文献

The purpose of the present study was to explore the phonological working memory of adults who stutter through the use of a non-word repetition and a phoneme elision task. Participants were 14 adults who stutter (M=28 years) and 14 age/gender matched adults who do not stutter (M=28 years). For the non-word repetition task, the participants had to repeat a set of 12 non-words across four syllable lengths (2-, 3-, 4-, and 7-syllables) (N=48 total non-words). For the phoneme elision task, the participants repeated the same set of non-words at each syllable length, but with a designated target phoneme eliminated. Adults who stutter were significantly less accurate than adults who do not stutter in their initial attempts to produce the longest non-words (i.e., 7-syllable). Adults who stutter also required a significantly higher mean number of attempts to accurately produce 7-syllable non-words than adults who do not stutter. For the phoneme elision task, both groups demonstrated a significant reduction in accuracy as the non-words increased in length; however, there was no significant interaction between group and syllable length. Thus, although there appear to be advancements in the phonological working memory for adults who stutter relative to children who stutter, preliminary data from the present study suggest that the advancements may not be comparable to those demonstrated by adults who do not stutter. EDUCATIONAL OBJECTIVES: At the end of this activity the reader will be able to (a) summarize the nonword repetition data that have been published thus far with children and adults who stutter; (b) describe the subvocal rehearsal system, an aspect of the phonological working memory that is critical to nonword repetition accuracy; (c) employ an alternative means to explore the phonological working memory in adults who stutter, the phoneme elision task; and (d) discuss both phonological and motoric implications of deficits in the phonological working memory.  相似文献

Deaf individuals rely on facial expressions for emotional, social, and linguistic cues. In order to test the hypothesis that specialized experience with faces can alter typically observed gaze patterns, twelve hearing adults and twelve deaf, early-users of American Sign Language judged the emotion and identity of expressive faces (including whole faces, and isolated top and bottom halves), while accuracy and fixations were recorded. Both groups recognized individuals more accurately from top than bottom halves, and emotional expressions from bottom than top halves. Hearing adults directed the majority of fixations to the top halves of faces in both tasks, but fixated the bottom half slightly more often when judging emotion than identity. In contrast, deaf adults often split fixations evenly between the top and bottom halves regardless of task demands. These results suggest that deaf adults have habitual fixation patterns that may maximize their ability to gather information from expressive faces.  相似文献

Existing data demonstrate a developmental trend in the way in which highly familiar faces are recognized, such that young children rely more on the outer facial features (the hairline, chin and ears) than the inner facial features (the eyes, nose and mouth) and adults demonstrate the reverse pattern. However, little is known about the developmental pattern of importance of inner and outer facial features for recognizing people who are not highly familiar. Here we report a study which attempts to describe this pattern. Using a two‐alternative forced‐choice procedure, we presented 5‐, 7‐, and 9‐year‐olds and adults (N = 22 in each group) with the task of recognizing an experimentally familiarized face (initially seen in a short video) from a still picture of either the whole face, just the inner, or just the outer parts. The results showed that, for all ages, recognition was faster (and in most cases, more accurate) for outer features alone than for inner features alone (and was fastest for whole faces). These data demonstrate the importance of outer facial features for the recognition of relatively unfamiliar faces. Taken together with previous findings, they enhance our picture of the effects of age and experience with individual faces on recognition and configural processing.  相似文献
