Post-divorce adaptation and the attribution of responsibility

A study was conducted to explore the possible relationship between post-divorce adjustment and the attributions divorced women give for the failure of their marriages. The study revealed that significantly more subjects who attributed their divorces to interactive rather than personal factors were more active, more socially skilled, happier, more optimistic, and less likely to blame themselves rather than outside forces for failures. The findings were also analyzed in light of whether or not subjects had initiated their divorce proceedings. The importance of making interactive attributions was discussed.We would like to thank Cynthia Weinman for her help in conducting the study. We are also grateful to the City University of New York for providing the funds for this research.     

Why be moral: Humanist and behavioral perspectives

Students of philosophy have struggled with the question, “Why should I be moral?” Many diverse theorists have constructed elaborate logical arguments that explain why people in general should behave morally, but have had difficulty explaining why any given individual, safe from detection or retribution, should behave in a moral fashion. To avoid this problem, the notion of a supernatural deity (one who is always watching and thus removes the notion of nondetection and nonretribution) has been introduced by numerous thinkers. Philosophical systems that pride themselves on being based only on natural phenomena, however, can make no such recourse (leading to the charge, particularly from the religious, that without a god concept there can be no morality). Naturalistic humanists and behavior analysts are two groups who have found themselves unable to invoke a deity and thus face the question “Why should I behave morally?” Parallel attempts from both camps will be described and analyzed, with the conclusion being drawn that although such naturalists may not be better off than their more religious friends, they are certainly no worse off.     

Learning the functional significance of mnemonic actions: A microgenetic study of strategy acquisition

How children learn to use memory strategies in a microgenetic investigation of learning and metacognition is examined. Seven- and eight-year-olds were given two memory trials with 24 pictures on each of 5 consecutive days. Days 1 and 2 were baseline, practice trials; Day 3 included strategy training; and Days 4 and 5 were unprompted tests of strategy maintenance. All children were taught how to label, rehearse, and group the pictures as well as to self-test their own memories and use blocked recall. Half of the children were shown the actions and told to do them; the other half received elaborated feedback on the usefulness and appropriateness of the techniques for remembering. The elaborated instructional group exhibited significantly greater recall, clustering, strategic study behavior, and metamemory regarding the mnemonic techniques than the other group. Path analysis provided evidence of a causal role of training and metacognitive awareness that mediated the use of sorting and higher recall. The study illustrates how learning the significance and utility of mnemonic techniques can influence children's acquisition of the tactics as self-controlled strategies. In addition, the microgenetic method affords patterns of data across time and experience that permit richer interpretations of strategy learning and memory development.     

The role of gradients of binocular disparity in Gibson’s theory of space perception

Adult Ss made distance bisection judgments over a surface on which the packing density of the texture elements was progressively increased along the Ss’ line of sight from one end of the surface to the other. Distance judgments were significantly different under monocular and binocular conditions of vision; however, with binocular vision, Ss did not detect the deformation in the texture on the surface. This result does not support predictions derived from Gibson, Purdy, and Lawrence (1955) concerning the role of gradients of binocular disparity in Gibson’s psychophysical theory of space perception.     

Does finger sense predict addition performance?

The impact of fingers on numerical and mathematical cognition has received a great deal of attention recently. However, the precise role that fingers play in numerical cognition is unknown. The current study explores the relationship between finger sense, arithmetic and general cognitive ability. Seventy-six children between the ages of 5 and 12 participated in the study. The results of stepwise multiple regression analyses demonstrated that while general cognitive ability including language processing was a predictor of addition performance, finger sense was not. The impact of age on the relationship between finger sense, and addition was further examined. The participants were separated into two groups based on age. The results showed that finger gnosia score impacted addition performance in the older group but not the younger group. These results appear to support the hypothesis that fingers provide a scaffold for calculation and that if that scaffold is not properly built, it has continued differential consequences to mathematical cognition.     

The effect of providing choices on skill acquisition and competing behavior of children with autism during discrete trial instruction

Discrete trial instruction was carried out for three students with autism. An alternating treatments design was implemented. In one condition, teachers chose the reinforcers to be used and the order in which programs were conducted. In a second condition, students chose the order of programs and the reinforcers to be used. Speed of skill acquisition and the presence of competing behavior such as tantrums, aggression, escape attempts or idiosyncratic noncompliance responses were measured. Speed of skill acquisition did not differ between the two conditions, but competing behavior was markedly reduced during student choice conditions. Copyright © 2002 John Wiley & Sons, Ltd.     

A neural network model of retrieval-induced forgetting

Retrieval-induced forgetting (RIF) refers to the finding that retrieving a memory can impair subsequent recall of related memories. Here, the authors present a new model of how the brain gives rise to RIF in both semantic and episodic memory. The core of the model is a recently developed neural network learning algorithm that leverages regular oscillations in feedback inhibition to strengthen weak parts of target memories and to weaken competing memories. The authors use the model to address several puzzling findings relating to RIF, including why retrieval practice leads to more forgetting than simply presenting the target item, how RIF is affected by the strength of competing memories and the strength of the target (to-be-retrieved) memory, and why RIF sometimes generalizes to independent cues and sometimes does not. For all of these questions, the authors show that the model can account for existing results, and they generate novel predictions regarding boundary conditions on these results.     

Racial groups and test fairness, considering history and construct validity

According to Helms, "test fairness" is defined as "removal from test scores of systematic variance attributable to experiences of racial or cultural socialization." Some of Helms's reasoning is based on earlier work, which recommended that racial group or category variables be replaced entirely with individual-level constructs, to reflect racial socialization experiences that vary within racial groups. Treatment of the test fairness issue--a social and political issue--will benefit from explicitly considering historical events that contributed to group-level race differences. In light of this history, D. A. Newman et al suggest (a) retaining a group-level conceptualization of race/racial socialization and also (b) focusing on criterion-irrelevant variance in test scores that is attributable to race.
