Recognition memoryfor pictorial events

Subjects viewed sequences of slides depicting everyday events, and in later recognition tests, they correctly rejected distractors that were inconsistent with some invariant of the event but falsely accepted consistent distractors. J. J. Jenkins has accounted for the differential recognition of consistent and inconsistent slides of pictorial sequences in terms of fusion, the abstraction of an event from a series of temporally related items. The conditions under which event fusion was likely to occur were manipulated in three experiments: degree of ordering of the action-sequence slides, semantic vs. nonsemantic orienting tasks during acquisition, and duration of retention interval Recognition performance was generally more accurate under conditions of semantic processing, ordered acquisition sequences (for the semantic task), and shorter retention intervals. However, these variables did not affect differential recognition of consistent vs. inconsistent slides. A further experiment showed that the absence of an effect of disordering acquisition sequences on differential recognition could not be attributed to subjects’ reordering the disordered sequences in a way consistent with the original event. The data did not support the hypothesis that recognition performance was based on fusion of events depicted by temporally ordered slide sequences. It was suggested that memory for featural detail is a relevant factor in performance.     

Prominent publications in cognitive psychology

This article identifies the 50 publications in cognitive psychology that were most frequently cited in the professional literature between 1979 and early 1982. The characteristics of these publications are discussed, and comparisons are made with other relevant findings.     

Mouse killing in rats induced by lesions of the medial hypothalamus or medial accumbens: short-term preoperative exposure to a mouse does not suppress the killing

Rats were either exposed or not exposed to a mouse in their living cage for a 48-hr period. At the end of this time a bilateral lesion was made in the medial accumbens region or in the medial hypothalamus. When tested 2 days postoperatively, the killing frequency among rats that had been exposed to mice preoperatively was not significantly lower than that of rats that were not preoperatively exposed. The ineffectiveness of preoperative experience in suppressing the mouse killing induced by medial accumbens and medial hypothalamic lesions is similar to that found previously with dorsal-median raphe lesions and olfactory bulb lesions and is in contrast to the ease with which preoperative experience prevents mouse killing induced by septal lesions and serotonergic lesions induced by 5,7-dihydroxytryptamine.     

Structural and strategic approaches to psychosomatic families.

Patterns of relatedness characteristic of psychosomatic families are discussed. A step-wise intervention procedure based on structural and strategic approaches is presented. The goals of the procedure are to establish symptomatic relief and modify concurrently the patterns of relatedness. The procedure is applied to a sample of families in which a child presents with psychogenic abdominal pain. This paper is intended as a detailed and practical guide to working with such families; a degree of generalization is possible, as well.     

Increasing Career Center Accessibility for the Blind

To improve career planning services for visually impaired persons, the career center at Florida State University developed a self-directed program. This article describes strategies for making career information materials and resources more accessible to the blind.     

Probabilities of homomorphic mappings from multiple graphs

Each partition of a population defines a homomorphic mapping of sociometric graphs onto a corresponding set of image graphs. For sets of images selected by substantive importance, the expected number of mappings is calculated when the array of sociometric graphs is drawn at random with equal probabilities. Upper and lower bounds are computed for the probability of finding at least one mapping from an array to the given images, and for the expected number of mappings given that there is at least one. Results of small Monte Carlo trials are reported.     

Independent effects of achievement motivation and overt attribution on achievement behavior

The cognitive attribution theory of achievement motivation was examined in a series of three studies. The persistence of performance under failure feedback was investigated, with improvement over trials on a digit-symbol substitution task constituting the measure of persistence. Although evidence was obtained relating overt causal attributions of failure to persistence, partial correlation statistics indicated that this relationship was independent of achievement motivation. Partial correlation statistics also revealed that the relationship between achievement motivation and persistence was independent of attributional variables. In addition, greater persistence was exhibited by high- than by low-achievement subjects in the absence of attribution differences between these groups. Additional evidence was collected suggesting that the act of overt attribution was an ego-involving operation that led to these achievement differences in improvement. In general, achievement classification and overt causal attributions had separate effects on persistence, precluding the interpretation of achievement-related behavior in terms of attribution theory. Overt causal attributions were found to be, in part, a function of the ego-involving character of the task instructions, as was improvement.Portions of this research were conducted while L. A.
