The serial pattern found for conjunction visual-search tasks has been attributed to covert attentional shifts, even though the possible contributions of target location have not been considered. To investigate the effect of target location on orientation × color conjunction searches, the target’s duration and its position in the display were manipulated. The display was present either until observers responded (Experiment 1), for 104 msec (Experiment 2), or for 62 msec (Experiment 3). Target eccentricity critically affected performance: A pronounced eccentricity effect was very similar for all three experiments; as eccentricity increased, reaction times and errors increased gradually. Furthermore, the set-size effect became more pronounced as target eccentricity increased, and the extent of the eccentricity effect increased for larger set sizes. In addition, according to stepwise regressions, target eccentricity as well as its interaction with set size were good predictors of performance. We suggest that these findings could be explained by spatial-resolution and lateral-inhibition factors. The serial self-terminating hypothesis for orientation × color conjunction searches was evaluated and rejected. We compared the eccentricity effect as well as the extent of the orientation asymmetry in these three conjunction experiments with those found in feature experiments (Carrasco & Katz, 1992). The roles of eye movements, spatial resolution, and covert attention in the eccentricity effect, as well as their implications, are discussed. 相似文献

Evidence is presented that implicates two factors in deductive reasoning about causality. The factors are alternative causes and disabling conditions (factors that prevent effects from occurring in the presence of viable causes). A causal analysis is presented in which these factors impact on judgments concerning causal necessity and sufficiency, which in turn determine deductive entailment relations. In Experiment 1, these factors were found to impact causal deductive judgments more strongly than did logical form. In Experiment 2, causal deductive judgments were found to vary as a function of familiarity with a particular causal relationship: The more familiar the causal relationship, the less willing reasoners were to accept conclusions based on them. 相似文献

One hundred and eighty four grade 6 and 7 students processed 32 factual statements in one of two studies reported here. Half the statements were consistent with the students' prior knowledge, whereas the remaining facts were inconsistent with it. Students studied the facts alone, or with a partner, by: (1) answering 'why' questions; (2) reading the information for understanding; or (3) selecting their own method of study. Recall (free and cued) and recognition measures (immediate, 30-day, and 60-day) were used to assess learning (immediate, 30-day, and 60-day). Instructions to use elaborative interrogation produced superior learning gains relative to instructing students to read information for understanding or to select their own study strategy. Overall, there were no performance differneces as a function of individual versus dyad study. The quality of the elaborative interrogation study response affected learning. When students generated or listened to a partner's response that clarified the target facts, learning of that information was superior to when students generated or listened to other types of study responses. 相似文献

This article discusses the construct of career maturity and briefly reviews research that identifies factors associated with this construct. Brief reviews of 6 instruments designed to measure career maturity are included: The Career Maturity Inventory (Crites, 1978a, 1978b), the Career Development Inventory (Super, Thompson, Lindeman, Jordaan, & Myers, 1988), the Adult Career Concerns Inventory (Super, Thompson, & Lindeman, 1988), the Assessment of Career Decision Making (Harren, 1979; Buck & Daniels, 1985), the Career Beliefs Inventory (Krumboltz, 1994), and the Career Decision Scale (Osipow, Carney, Winer, Yanico, Koschier, 1976). Issues associated with the assessment of career maturity are also discussed. 相似文献

The purpose of this study was to evaluate the discriminant validity of scores from the Adolescent Behavior Checklist (ABC), a self-report measure of ADHD symptomatology for adolescents ages 11–17 years. Validity was assessed through correlational, univariate, and discriminant function analyses using three groups: (1) adolescents diagnosed with ADHD, (2) adolescents currently experiencing a mood and/or anxiety disorder, and (3) adolescents with no major psychological disorder. Convergent and divergent validity of the ABC factor scores was demonstrated through correlational results with (1) parent and adolescent report of ADHD symptoms during structured psychiatric interviews and (2) scores on questionnaires measuring related and nonrelated constructs. Univariate analyses indicated that the ADHD group obtained significantly higher scores than did the nonclinical adolescents across all ABC factors. Additionally, the ADHD group scored significantly higher than did the psychiatric controls on the following ABC factors: Conduct Problems, Impulsivity/Hyperactivity, and Social Problems. Results from discriminant analyses supported the reliability of ABC scores in correctly classifying participants into groups. Compared to the Youth Self-Report, the ABC was found to be somewhat better at classifying when used in a multiinformant discriminant analysis. Therefore, overall results from the current study suggest that the ABC is a valid and useful self-report screening measure for ADHD symptoms and related difficulties. 相似文献

The Stein paradigm was used to examine the circumstances under which verbal elaborations enhance memory in young and older adults. Subjects studied target adjectives that were embedded in one of three sentence contexts that varied in elaboration of the subject-adjective relationship: (1) nonelaborated base sentences; (2) base sentences with semantically consistent, but arbitrary verbal, elaborations; and (3) base sentences with explanatory verbal elaborations that clarified the significance of the subject-adjective relationship. The presence of the elaborations was varied at encoding and retrieval, and cued recall of the target adjectives was tested with incidental and intentional learning procedures. In Experiments 1A and 1B, explanatory elaborations at encoding and retrieval yielded the largest memorial facilitation for both young and older adults, and the benefit was comparable for the incidental and intentional learning measures. In Experiment 2, age-related differences in recall were minimal with explanatory elaborations at encoding and retrieval, but larger age differences occurred in the nonelaborated comparison conditions. In Experiment 3, explanatory elaborations present at encoding but not at retrieval enhanced recall when the original Stein stimuli were used, but not with the present stimuli. The implications of these results with regard to the mnemonic efficacy of verbal elaborations for young and older adults are discussed. 相似文献

The effect of a nonverbal behavior frequently displayed during social interaction, self-touching, was analyzed with respect to body location, other nonverbal behaviors, and expressers' role. In Study 1, hypotheses about role (job applicant, medical patient, friend, stranger) and levels of anxiety and familiarity were substantiated. In Study 2, subjects rated females who displayed several types of self-touching (to nose, arm, hand) singly, or in combination with head nodding or leg recrossing, representing the four roles in Study 1. Hypotheses based on types of self-touching and role were supported by linear contrasts; for example, hand rubbing by job applicant and patient, who were expected to experience some anxiety, was judged as more acceptable than for friend or stranger. Discrete self-touching (nose) was evaluated as more expressive and warm than unpatterned self-touching (hand, arm) for friend and stranger. Control scenes (no movement) were rated as more calm and dominant, but less expressive, warm, and interested. 相似文献

Choice of units of analysis is a critical problem in evaluating environmental assessment items. The “Ecological Fallacy” involves
interpreting results based on ecological entities, such as environmental settings, as applying to individuals. A less familiar
error, the “Individual Differences Fallacy,” involves interpreting results based on individuals as applying to settings. Although
this second error has been ubiquitous, little is known about the empirical consequences of using different units of analysis
in item analysis. This study examined this issue when the units were (1) individuals, (2) observed settings, or (3) “artificial”
or random settings. Neither item validities based on individuals nor item validities based on settings yielded unequivocal
results. However, a measure developed specifically for environmental research, the Split-Sample Correlation, appeared useful
for identifying environmental items. Researchers constructing environmental assessment scales should select items with both
high Split-Sample Correlations and high setting-level item validities. 相似文献
