Coping with threat and memory for ambiguous information: testing the repressive discontinuity hypothesis

Two studies examined the influence of coping dispositions (repression, sensitization, and nondefensiveness) and anxiety on the encoding and memory representation of ambiguous threat-related stimuli. In Study 1, memory was tested shortly after encoding. Study 2 contrasted immediate and delayed testing. Repressers showed evidence of "mixed" affective reactions to ambiguous stimuli at encoding, accompanied by weak memory representation of potentially threatening implications of these stimuli. In contrast, sensitizers and anxious individuals manifested a processing bias in favor of threatening implications of ambiguous stimuli. Influences of coping on memory were most pronounced for delayed testing. Anxiety influences on memory were weak. An expectancy-based account of individual differences in processing ambiguous stimuli is discussed.     

Comparing learning environments in U.S. military officer education: a brief replication

A 2003 comparative study on learning environments at two military officer training sites was replicated using different methodology. Satisfaction with learning environment and with administrative inprocessing was higher at Fort Leavenworth than at Fort Dix. Most students expressed a preference for Fort Leavenworth. Satisfaction with institutional support and educational facilities appears to influence perceived satisfaction with a learning environment and with preference for training sites among senior military officers.     

Placing the perceptual-cognitive approach in perspective

Although some features of the "psychological approach" are compelling, its immediate impact as a theoretical framework appears to be limited by somewhat ambiguous key constructs and the lack of appropriate placement vis-a-vis extant conceptual views.     

Visual masking during the attentional blink: tests of the object substitution hypothesis

When 2 masked targets are presented in a rapid sequence, correct identification of the 1st hinders identification of the 2nd. Visual masking of the 2nd target plays a critical role during this 2nd-target deficit, or "attentional blink" (AB). The object substitution hypothesis (B. Giesbrecht & V. Di Lollo, 1998) predicts that late-stage visual processes involved in object substitution mediate masking of the 2nd target during AB, whereby stronger masking should produce a more severe deficit. Six experiments are presented, together testing this hypothesis. Although masking by object substitution was observed, it did not interact with the AB. An alternative hypothesis is proposed stating that mostly early-stage visual processes mediate the masking effects that are critical to the AB.     

Return of the ego--self-referent information as a filter for social prediction: comment on Karniol (2003)

The protocentrism paradigm of social prediction (R. Karniol, 2003) challenges the egocentrism paradigm tacitly accepted by many researchers. The author reviews the 2 paradigms comparatively by focusing on 3 conceptual and 3 empirical issues. On conceptual grounds, the author suggests that the egocentrism paradigm has been proven useful because of (a) its greater breadth and parsimony, (b) the difficulties in documenting the origin of protocenters, and (c) the indeterminate nature of self-as-distinct tags (which are crucial to protocentrism). On empirical grounds, the author argues that in research on perceptions of self-other similarities, the egocentric process of social projection is well-established. Self-referent knowledge (a) is most readily accessible, (b) receives greater weight in prediction tasks than does other-referent knowledge, and (c) tends to be suppressed only temporarily, with effort, and incompletely.     

Interpreting past religious discrimination today

Much of modern western law now presupposes opposition to discrimination based on race, religion, sex, national origin, and other factors. However, ancient religious Scriptures may have sanctioned certain types of discrimination. Whether those who are inclined to accept literal interpretations of their Scriptures will condone certain forms of discrimination could be evaluated to contrast the effects of modernization versus religious indoctrination on various kinds of prejudice.     

Preservation of autobiographical memory in a case of pure progressive amnesia

G.D., a 79 year-old female, presents with a severe and slowly progressive amnesia although she remains entirely independent in daily life and is perfectly well spatially oriented. Her amnesia is relatively isolated and her deficit does not embrace other cognitive domains. G.D. underwent extensive neuropsychological evaluation including language, executive functions, perceptual, and memory tests. Based on clinical observation, the purpose of this study was to determine whether there was a dissociation between her autobiographical and semantic memory. Results point out a severely degraded semantic knowledge of famous public events and persons while autobiographical memory of personally experienced and relevant information remains intact. Results from this study and from previous studies seem to suggest that relative sparing of hippocampal structures may be related to the preservation of autobiographical memory.
