REINFORCER VARIATION: IMPLICATIONS FOR MOTIVATING DEVELOPMENTALLY DISABLED CHILDREN

Motivating developmentally disabled children to participate in educational activities can be very difficult. This is especially true for children diagnosed autistic. Because there is some evidence to suggest that stimulus variation may influence motivation, the present study investigated the effects of constant vs. varied reinforcer presentation on correct responding and on-task behavior. Results from a reversal design showed declining trends in both correct responding and on-task behavior when the same reinforcer was consistently presented, whereas, varying the reinforcers produced significantly improved and stable responding. The results are discussed in relation to the literature on stimulus variation and its effects on responsivity.     

The Effects of Alcohol Use and Offender Remorsefulness on Sentencing Decisions1

Presentence reports on 628 offenders were content analyzed. Regression analysis found that remorseful offenders received less severe sentences than non-remorseful offenders. Offenders convicted of minor offenses received more lenient sentences if they had used alcohol in conjunction with their crimes than if they did not use alcohol. The opposite was the case for offenders commiting serious crimes. Remorseful offenders with few prior alcohol-related convictions received less severe sanctioning than non-remorseful offenders with similar conviction records. In contrast, recidivists who were remorseful were dealt with more harshly than their non-remorseful counterparts.     

A tempest, a birth, and death: Freud, Jung, and Shakespeare’sPericles

This essay applies a Freudian psychoanalytic and Jungian archetypal narrative analysis to Shakespeare’s first and oft-criticized romance. The author argues that key structural and thematic elements ofPericles are best illuminated when viewed through a psychological interpretative lens, and that the play is best comprehended when examined in the context of its associative, rather than linear, richness. Masculinity and femininity, central themes of the narrative, are explored both in relation to the Oedipal complex and psychological individuation.Pericles also provides an excellent basis to examine key differences between Freud’s and Jung’s approach, particularly Jung’s widening of the primarily sexual psychoanalytic approach to encompass broader archetypal meaning.     

Contemporary Environmental Ethics From Metaethics to Public Philosophy

In the past thirty years environmental ethics has emerged as one of the most vibrant and exciting areas of applied philosophy. Several journals and hundreds of books testify to its growing importance inside and outside philosophical circles. But with all of this scholarly output, it is arguably the case that environmental ethics is not living up to its promise of providing a philosophical contribution to the resolution of environmental problems. This article surveys the current state of the field and offers an alternative path for the future development of environmental ethics toward a more publicly engaged model of applied philosophy.     

Anxiety-related bias in the classification of emotionally ambiguous facial expressions

High- and low-trait socially anxious individuals classified the emotional expressions of photographic quality continua of interpolated ("morphed") facial images that were derived from combining 6 basic prototype emotional expressions to various degrees, with the 2 adjacent emotions arranged in an emotion hexagon. When fear was 1 of the 2 component emotions, the high-trait group displayed enhanced sensitivity for fear. In a 2nd experiment where a mood manipulation was incorporated, again, the high-trait group exhibited enhanced sensitivity for fear. The low-trait group was sensitive for happiness in the control condition. The mood-manipulated group had increased sensitivity for anger expressions, and trait anxiety did not moderate these effects. Interpretations of the results related to the classification of fearful expressions are discussed.     

Change in cognitive functioning associated with apoE genotype in a community sample of older adults

The influence of a genetic risk factor, apolipoprotein E (apoE) epsilon4 variant, was assessed in older adults aged 70 to 94 on 3 occasions over 7 years. The results of latent growth curve analyses are reported for individuals genotyped for apoE at the 2nd measurement occasion (n = 601) and for a subsample of individuals without probable or definite dementia during the 1st or 2nd occasion (n = 434). ApoE-epsilon4 status was a significant predictor of level and change in memory performance and change in speed performance in the full sample, and of initial level and change in memory performance in the nondemented subsample. These results support previous findings that apoE-epsilon4 is associated with accelerated memory deterioration in individuals without clinical dementia.     

Contribution of color to face recognition

One of the key challenges in face perception lies in determining how different facial attributes contribute to judgments of identity. In this study, we focus on the role of color cues. Although color appears to be a salient attribute of faces, past research has suggested that it confers little recognition advantage for identifying people. Here we report experimental results suggesting that color cues do play a role in face recognition and their contribution becomes evident when shape cues are degraded. Under such conditions, recognition performance with color images is significantly better than that with gray-scale images. Our experimental results also indicate that the contribution of color may lie not so much in providing diagnostic cues to identity as in aiding low-level image-analysis processes such as segmentation.     

The importance of eyes: how infants interpret adult looking behavior

Two studies assessed the gaze following of 12-, 14-, and 18-month-old infants. The experimental manipulation was whether an adult could see the targets. In Experiment 1, the adult turned to targets with either open or closed eyes. Infants at all ages looked at the adult's target more in the open- versus closed-eyes condition. In Experiment 2, an inanimate occluder, a blindfold, was compared with a headband control. Infants 14- and 18-months-old looked more at the adult's target in the headband condition. Infants were not simply responding to adult head turning, which was controlled, but were sensitive to the status of the adult's eyes. In the 2nd year, infants interpreted adult looking as object-directed--an act connecting the gazer and the object.     

Power,Leadership, and Self‐Regulation

Power has been linked to both self‐regulatory success and failure. Power typically aids self‐regulation of task performance by making people motivated and goal‐oriented. However, because people’s self‐regulatory resources are limited, as powerful people exert effort on their focal tasks, they may fail to self‐regulate in other domains. This type of goal myopia may lead to detriments in impulse control. Wielding power, by making decisions and leading subordinates, can deplete people’s self‐regulatory resources, making subsequent acts of self‐control more difficult.
