At-Risk Urban High School Students' Commitment to Career Choices

The purpose of this study was to examine the commitment to career choices process for at-risk urban high school students. Data from 189 at-risk urban high school students were sampled. Results indicated that students' level of commitment to their career choices was related to their vocational identity, their need for occupational information, their perceived barriers to occupational goals, and the number of occupations they considered. The tendency to foreclose was related to the adherence to career myths. Implications and limitations for career theory, research, and practice are addressed.     

Coreference processing and levels of analysis in object-relative constructions; Demonstration of antecedent reactivation with the cross-modal priming paradigm

This paper is concerned with two related issues in sentence processing-one methodological and one theoretical. Methodologically, it provides an unconfounded test of the ability of the cross-modal lexical priming task, when used appropriately, to provide detailed evidence about the time-course of antecedent reactivation during sentence processing. Theoretically, it provides a study of the nature of the representation that is examined when a reference-seeking element is linked to its antecedent during the processing of object-relative clause constructions. In these studies, subjects heard sentences which contained a lexical ambiguity placed in a strong biasing context. In one study this ambiguous word was the moved or fronted object of the verb in an object-relative construction. A cross-modal lexical priming (CMLP) naming task was used to determine whether one or more of the meanings of the ambiguity are activated at three temporally distinct points during the sentence: (1) immediately after the lexical ambiguity (Study 1); (2) a later point that was 700 milliseconds before the offset of the main verb (Study 2); (3) immediately after this main verb (at the gap in this filler-gap construction) (Study 2). The probes in the CMLP task were controlled for potential confounds. The results demonstrate the following: At Test Point 1, all meanings of the ambiguity were activated; at Test Point 2, neither meaning of the ambiguity was (still) activated; at Test Point 3, only a single (context-relevant) meaning of the ambiguity was reactivated. It is concluded that an underlying (deep; non-surface-level) memorial representation of the sentence is examined during the process of linking an antecedent to a structural position requiring a referent, and that the CMLP task provides an unbiased measure of this reactivation. Further, it is concluded that this effect cannot be accounted for under a compound cue (Ratcliff & McKoon, 1994) explanation.The authors gratefully acknowledge the contributions of an anonymous reviewer for helpful suggestions and changes in this paper, and the support of a fellowship to the first author from grant T32 DC 00041 and NIH grant ROI DC00494 (to the second author) for this work.     

Rehearsal in Spatial Working Memory: Evidence From Neuroimaging

A variety of biological evidence has identified a frontal-parietal circuit underlying spatial working memory for visual stimuli. But the question remains, how do these neural regions accomplish the goal of maintaining location information on-line? We tested the hypothesis that the active rehearsal of spatial information in working memory is accomplished by means of focal shifts of spatial selective attention to memorized locations. Spatial selective attention has been shown to cause changes in the early visual processing of stimuli that appear in attended locations. Thus, the hypothesis of attention-based rehearsal predicts similar modulations of visual processing at memorized locations. We used functional magnetic resonance imaging to observe posterior visual activations during the performance of a spatial working memory task. In line with the hypothesis, spatial rehearsal led to enhanced activation in the early visual areas contralateral to the memorized locations.     

The Construct Validity of Assessment Centre Performance Dimensions

Evidence regarding the construct validity of assessment centre performance dimensions is reviewed. The evidence strongly suggests that variance in ratings tends to reflect exercises more than individual performance dimensions, thus calling into question the construct validity and utility of these dimensions. A number of biases in the assessment centre process, as well as more general rating biases are noted that may be responsible for these pervasive exercise effects. Suggestions are made for enhancing the construct validity of performance dimensions.     

The effect of temporal and force changes on the patterning of sequential movements

Summary This article examines the programming of relatively long sequences of action with the control of sequential movements being effected through the use of a tapping task involving a sequence of five taps. Subjects were required to tap with their right hand at rates of 150, 200, and 250 ms. There were two conditions, with subjects being required either to increase, in condition 1, or to decrease, in condition 2, the force at one of the five tap positions (all five tap positions were examined), then return to the previous force level. Changes in timing resulting from variations in the force characteristics have previously been discussed in terms of changes in the organizational time required ( Semjen, Garcia-Colera, & Requin, 1984). The current study breaks the intertap interval down into two separate components: the contact interval (finger in contact with the key) and the non-contact interval (interval preceding the tap). Although changes in the non-contact interval could be explained in terms of changes in the organizational time required, changes in the contact interval appeared to be a result of the mechanical changes in force.     

Hurricane Andrew: Psychological distress among shelter victims

This study examined psychological distress and functioning among Hurricane Andrew victims who lost their homes and were living in shelters. Four and one-half weeks after Hurricane Andrew struck southern Florida, 89 (45 males, 44 females) Blacks, Hispanics, and Whites completed a questionnaire. The questionnaire asked for information about psychological and psychophysiological symptoms, use of mental health services, coping responses, and extent of preparation for the storm. The findings suggest that loss of home and property were related to distress and depression. About one-quarter of the sample were moderately depressed. Over one-third of the sample reported experiencing psychological and psychophysiological distress. Approximately one-half of the subjects did not take the hurricane warnings seriously. White subjects began preparing earlier for the storm, and evacuated their homes more frequently than did Black subjects. Implications of the findings and future research directions are discussed.

Anticipatory emotions in decision tasks: Covert markers of value or attentional processes?

Anticipatory emotions precede behavioral outcomes and provide a means to infer interactions between emotional and cognitive processes. A number of theories hold that anticipatory emotions serve as inputs to the decision process and code the value or risk associated with a stimulus. We argue that current data do not unequivocally support this theory. We present an alternative theory whereby anticipatory emotions reflect the outcome of a decision process and serve to ready the subject for new information when making an uncertain response. We test these two accounts, which we refer to as emotions-as-input and emotions-as-outcome, in a task that allows risky stimuli to be dissociated from uncertain responses. We find that emotions are associated with responses as opposed to stimuli. This finding is contrary to the emotions-as-input perspective as it shows that emotions arise from decision processes.
