This study examined the effects of sibship size and birth order on episodic memory performance in adulthood and old age. Participants were 1,141 healthy individuals aged 35–80 years, who took part in a longitudinal project on age, health, and memory. Episodic memory measurements over a 5-year interval included tests of recognition (recognition of faces, family names, first names, and nouns) and tests of recall (free recall of sentences, free recall and cued recall of nouns, and recall of activities). Results showed significant effects for both recall and recognition, that is, the smaller the sibship size is for an individual and the earlier born, the better memory performance. These results demonstrate that the effects of sibship size and birth order previously shown in children and adolescents (Belmont and Marolla, Science 182:1096–1101, 1973; Zajonc and Markus, Psych Rev 82:74–88, 1975; Zajonc, Am Psychol 56:490–496, 2001) are robust over time and hold over a large adult range.  相似文献

Cues that chimpanzees do and do not use to find hidden objects   总被引:7,自引:7,他引:0  
Chimpanzees follow conspecific and human gaze direction reliably in some situations, but very few chimpanzees reliably use gaze direction or other communicative signals to locate hidden food in the object-choice task. Three studies aimed at exploring factors that affect chimpanzee performance in this task are reported. In the first study, vocalizations and other noises facilitated the performance of some chimpanzees (only a minority). In the second study, various behavioral cues were given in which a human experimenter either touched, approached, or actually lifted and looked under the container where the food was hidden. Each of these cues led to enhanced performance for only a very few individuals. In the third study – a replication with some methodological improvements of a previous experiment – chimpanzees were confronted with two experimenters giving conflicting cues about the location of the hidden food, with one of them (the knower) having witnessed the hiding process and the other (the guesser) not. In the crucial test in which a third experimenter did the hiding, no chimpanzee found the food at above chance levels. Overall, in all three studies, by far the best performers were two individuals who had been raised in infancy by humans. It thus seems that while chimpanzees are very good at “behavior reading” of various sorts, including gaze following, they do not understand the communicative intentions (informative intentions) behind the looking and gesturing of others – with the possible exception of enculturated chimpanzees, who still do not understand the differential significance of looking and gesturing done by people who have different knowledge about states of affairs in the world.

The production of meaningful gestures has been claimed to enhance lexical access. However, the possibility that meaningless movements also improve retrieval has been largely ignored despite evidence that all types of movements increase with dysfluency. To examine this issue, we conducted two experiments to determine whether movements in general would improve lexical access in a tip–of–thetongue (TOT) paradigm. TOT states were induced by presenting definitions of rare words that participants were then asked to recall. Participants who were required to tap at their own pace while retrieving words obtained significantly higher resolution rates than those who were immobile. Thus, movement does not have to be semantically related to the lexical item in order to aid in retrieval. However, tapping did not improve lexical access in all retrieval tasks. In a lexical retrieval task that relied more on executive abilities (letter fluency), participants who tapped retrieved fewer words than those who were immobile. The fact that movement enhanced lexical access only when retrieval depended on the automatic spread of activation suggests that facilitation may occur because of the activation of neural areas common to both speech and movement.  相似文献

Feedback processing is crucial for successful performance adjustment following changing task demands. The present event-related fMRI study was aimed at investigating the developmental differences in brain regions associated with different aspects of feedback processing. Children age 8–11, adolescents age 14–15, and adults age 18–24 performed a rule switch task resembling the Wisconsin Card Sorting Task, and analyses focused on different types of negative and positive feedback. All age groups showed more activation in lateral orbitofrontal cortex (OFC), anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), and superior parietal cortex following negative relative to positive performance feedback, but the regions contributed to different aspects of feedback processing and had separable developmental trajectories. OFC was adultlike by age 8–11, whereas parietal cortex was adultlike by age 14–15. DLPFC and ACC, in contrast, were still developing after age 14–15. These findings demonstrate that changes in separable neural systems underlie developmental differences in flexible performance adjustment.

The purpose of this study was to investigate how gender role incongruence in terms of women being primary wage earners and males being secondary wage earners in their families could affect them at work. Using an experimental design and a sample of 306 college students, I explored how females who are the primary wage earners in their families and males who are the secondary wage earners are perceived and evaluated in a work setting. I proposed, and found, that female primary wage earners are seen as the least overqualified and are given lower reward recommendations than equally qualified male peers (i.e., peers with exactly the same credentials and job performance). Male secondary wage earners are seen as being the most overqualified and are given higher reward recommendations than equally qualified female peers. Results demonstrate how the lack of fit model, which has been shown to penalize women who succeed in traditionally masculine domains (Dipboye, Acad Manag Rev 10:16–127, 1985; Heilman, Res Organ Behav 5:269–298, 1983, J Soc Issues 57:657–674, 2001), can be applied to situations where gender-incongruent behavior exists in the form of women being primary wage earners in their families. I refer to this phenomenon as “home-related spillover discrimination,” named after the spillover effects that derive from societal expectations that are transferred into employment situations (Nieva and Gutek, Acad Manag Rev 5:267–276, 1980). The practical implication of this finding is that this may present a new form of sex discrimination against women that has not yet been considered. This is the first study to show how violating stereotypical roles in terms of family wage earner status can influence outcomes in work settings.  相似文献

The paper discusses Heidegger's early notion of the “movedness of life” (Lebensbewegtheit) and its intimate connection with Aristotle's concept of movement (kinēsis). Heidegger's aim in the period of Being and Time was to “overcome” the Greek ideal of being as ousia – constant and complete presence and availability – by showing that the background for all meaningful presence is Dasein, the ecstatically temporal context of human being. Life as the event of finitude is characterized by an essential lack and incompleteness, and the living present therefore gains meaning only in relation to a horizon of un-presence and un-availability. Whereas the “theological” culmination of Aristotle's Nicomachean Ethics finds the supreme fulfillment of human life in the semi-divine self-immanence and self-sufficiency of the bios theōrētikos, a radical Heideggerian interpretation of kinēsis may permit us to find in Aristotle the fundamental structures of mortal living as self-transcendent movement.  相似文献

Previous research on gaze behaviour in sport has typically reported summary fixation statistics thereby largely ignoring the temporal sequencing of gaze. In the present study on penalty kicking in soccer, our aim was to apply a Markov chain modelling method to eye movement data obtained from goalkeepers. Building on the discrete analysis of gaze employed by Dicks et al. (Atten Percept Psychophys 72(3):706–720, 2010b), we wanted to statistically model the relative probabilities of the goalkeeper’s gaze being directed to different locations throughout the penalty taker’s approach (Dicks et al. in Atten Percept Psychophys 72(3):706–720, 2010b). Examination of gaze behaviours under in situ and video-simulation task constraints reveals differences in information pickup for perception and action (Attention, Perception and Psychophysics 72(3), 706–720). The probabilities of fixating anatomical locations of the penalty taker were high under simulated movement response conditions. In contrast, when actually required to intercept kicks, the goalkeepers initially favoured watching the penalty taker’s head but then rapidly shifted focus directly to the ball for approximately the final second prior to foot-ball contact. The increased spatio-temporal demands of in situ interceptive actions over laboratory-based simulated actions lead to different visual search strategies being used. When eye movement data are modelled as time series, it is possible to discern subtle but important behavioural characteristics that are less apparent with discrete summary statistics alone.  相似文献

In the present study, we examined adult age differences in short-term and working memory performance in middle-aged (45–64 years), young–old (65–74 years), old–old (75–89 years), and oldest–old adults (90 years and over) in the Louisiana Healthy Aging Study. Previous research suggests that measures of working memory are more sensitive to age effects than are simple tests of short-term memory Bopp and Verhaeghen (Journal of Gerontology: Psychological Sciences 60:223–233, 2005), Myerson, Emery, White, and Hale, (Aging, Neuropsychology, and Cognition 10:20–27, 2003). To test this hypothesis, we examined output serial position curves of recall data from three span tasks: forward and backward digit span and size judgment span. Participants’ recall patterns in the size judgment span task revealed that the two oldest groups of adults showed the largest decreases in recall performance across output serial positions, but did not differ significantly from each other. Correlation analyses indicated the strongest negative correlation with age occurred with the size judgment span task. Implications of these findings for understanding strategic processing abilities in late life are discussed.  相似文献

The viability of five prominent explanations for the black–white performance gap (“academic engagement,” “cultural capital,” “social capital,” “school quality” and “biased treatment”) is examined using NELS data and a LISREL model that adjusts for clustering of students within schools. Empirical models have typically assessed these factors individually—a practice that probably fosters overestimation of their explanatory power. School quality and biased treatment emerge as the primary explanations for black–white high school test performance differentials. Access to better-quality schools and receipt of more stimulating interpersonal “signals” from gatekeepers ensue from racial (and socioeconomic) privilege. Enhanced test performance in turn ensues from these resources. In essence, the explanations for the racial gap that place more emphasis on what black and white students “bring to” high school (i.e., specific levels of engagement, cultural and social capital), seem less consequential to performance differentials than “what happens to” them when they get there (i.e., quality of education provided, and race-contingent treatment received).  相似文献

This paper—originally a sermon––addresses issues involved with nuclear idolatry from a biblical perspective. It utilizes psychological understanding and historical narrative as a context for theological reflection. It thus places depth psychological insight in service of social ethics. It was delivered at the Church of the Epiphany, Manhattan, New York, on August 14, 2005. The Rev. Curtis Hart, M.Div, is Director of Pastoral Care and Education, and Lecturer in Public Health, Medicine,and Psychiatry, Division of Medical Ethics, at the Weill Cornell Center of New York Presbyterian Hospital in New York City.  相似文献

This paper describes a combined instrument (eye tracker and target generator, both head mounted, with integrated data analysis) that tests parameters of saccadic eye movement and fixation control to give insight into the status of functional brain systems. Using three minilasers, the target generator projects three visual stimuli, a fixation point and two lateral stimuli, with programmable timing. The controller allows the selection of overlap, 200-msec gap, or remembered saccade trials. Size, maximal velocity, and reaction time are determined for each primary saccade. The number of prosaccades and antisaccades are counted. More saccades—for example, the occurrence and latency of corrective saccades—may be evaluated off line by an interactive PC analysis program. The eye position data can be transferred to a PC. Off-line analysis compares each observed variable relative to an age-matched control group (300 healthy control subjects 7–70 years of age, tested in the overlap condition with prosaccade instructions and in the gap condition with antisaccades). The diagnostic results can be used to elaborate an individual optomotor training program.  相似文献

The purpose of this study was to compare the fundamental movement skills of 22 children with attention-deficit hyperactivity disorder (ADHD), from 6 to 12 years of age, to gender- and age-matched peers without ADHD and assess the effects of stimulant medication on the movement skill performance of the children with ADHD. Repeated measures analyses revealed significant skill differences between children with and without ADHD (p ≤ 0.001). Results from the stimulant medication trials indicated no significant effect of medication on the movement skill patterns of children with ADHD. It is concluded that children with ADHD may be at risk for developmental delays in movement skill performance. Potential factors underlying the movement skill difficulties are discussed, with suggestions for future research.  相似文献

There is a substantial number of Iranian war veterans, exposed to sulfur mustard, who suffer from serious long term progressive health problems involving their respiratory organs, eyes, and skin. Little is known, however, about these casualties’ experiences of living with the consequences of sulfur mustard poisoning. This qualitative study aims to provide greater insight into how war veterans live with the consequences of the poisoning and involved 17 Iranian war veterans who had been poisoned by sulfur mustard during the Iran–Iraq conflict. Each participant was interviewed using a semi-structured interview schedule and the data generated through this process was analyzed using constant comparative data analysis technique. Data analysis resulted in “religious beliefs and practices” as a main category, which included two sub-categories: religious value centered life and religious support. Findings suggest that religious belief assists veterans to accept the impact of poisoning on their lives and adapt their lifestyles accordingly, to participate in religious social activities and feel socially supported, and to be hopeful about the future and live their lives as fully as possible.  相似文献

The view that successful memory performance depends importantly on the extent to which there is a match between the encoding and retrieval conditions is commonplace in memory research. However, Nairne (Memory, 10, 389–395, 2002) proposed that this idea about trace–cue compatibility being the driving force behind memory retention is a myth, because one cannot make unequivocal predictions about performance by appealing to the encoding–retrieval match. What matters instead is the relative diagnostic value of the match, and not the absolute match. Three experiments were carried out in which participants memorised word pairs and tried to recall target words when given retrieval cues. The diagnostic value of the cue was varied by manipulating the extent to which the cues subsumed other memorised words and the level of the encoding–retrieval match. The results supported Nairne’s (Memory, 10, 389–395, 2002) assertion that the diagnostic value of retrieval cues is a better predictor of memory performance than the absolute encoding–retrieval match.  相似文献

In 1958, a group of New-Confucians issued “A Manifesto for a Re-Appraisal of Sinology and Reconstruction of Chinese Culture.” Equally in 1958, the British philosopher Elizabeth Anscombe published her classical paper “Modern Moral Philosophy.” These two papers have the same target — modern Western morality — and the solutions they proposed respectively. Yet Anscombe’s paper did not mention Confucianism, and the “Manifesto” ignored Aristotelian tradition of virtue. Furthermore, from 1960s to 1990s, the revival movement of Confucianism and the revival movement of Aristotelian ethics have not had much dialogue. This paper seeks to explain this phenomenon by comparing these two historically important documents. In particular it tries to understand why the “Manifesto” fails to see the similarities between Aristotle and Confucius.

This study examined different methods of combining data from a well established rating scale – the Disruptive Behavior Disorders Rating Scale (DBDRS) – with data from a well established interview – the computerized self report version of the Diagnostic Interview Schedule for Children for DSM-IV (P-DISC-IV) – when examining parent report of ADHD. These measures were completed for 80 children who participated in a summer camp for children with disruptive behavior. Results showed significant overlap between the two diagnostic measures but parent report on the DBDRS was more highly associated with children’s camp behaviors than was parent report on the P-DISC-IV. In addition, combining ratings and interview data using an “either/or” rule was more highly associated with camp behavior than was combining data using a “both/and” rule. Results suggest there may be little additional value of adding data from parent self-report on the computerized version of the P-DISC-IV to behavior rating data.  相似文献

We extend research on the priming of insight by studying group problem solving. Groups of 2–4 participants tried to solve an ambiguously worded problem in the presence of a prime that reinforced the dominant but incorrect interpretation of the problem, a prime that reinforced the uncommon but correct interpretation, or no prime. The paradigm involved participants asking questions of the experimenter that could only be answered “yes” or “no.” In Experiment 1, the prime was present throughout the solving period; in Experiment 2, it was removed prior to the solving period. In both experiments, the primes had their predicted effects. Patterns in the time taken to solve the problem supported the idea that groups stuck at the impasse were more or less able to restructure the problem, depending on the environmental context. Data from the questions asked and questionnaires converged with time taken to solve the problem, consistent with the view that restructuring a problem is an automatic process that produces insight. A comparison of the group data in Experiment 1 with individually tested participants’ data revealed that the insight of the groups benefited from their being able to recognize lines of questions to follow, to listen to answers to questions asked, and to evaluate and reject errors or assumptions.  相似文献

Hypothesis-testing performance on Wason’s (Quarterly Journal of Experimental Psychology 12:129–140, 1960) 2–4–6 task is typically poor, with only around 20% of participants announcing the to-be-discovered “ascending numbers” rule on their first attempt. Enhanced solution rates can, however, readily be observed with dual-goal (DG) task variants requiring the discovery of two complementary rules, one labeled “DAX” (the standard “ascending numbers” rule) and the other labeled “MED” (“any other number triples”). Two DG experiments are reported in which we manipulated the usefulness of a presented MED exemplar, where usefulness denotes cues that can establish a helpful “contrast class” that can stand in opposition to the presented 2–4–6 DAX exemplar. The usefulness of MED exemplars had a striking facilitatory effect on DAX rule discovery, which supports the importance of contrast-class information in hypothesis testing. A third experiment ruled out the possibility that the useful MED triple seeded the correct rule from the outset and obviated any need for hypothesis testing. We propose that an extension of Oaksford and Chater’s (European Journal of Cognitive Psychology 6:149–169, 1994) iterative counterfactual model can neatly capture the mechanisms by which DG facilitation arises.  相似文献
