The happy cyclist: Examining the association between generalized authoritarianism and subjective well-being

Although authoritarianism can negatively impact others (e.g., by predicting prejudiced intergroup attitudes), implications for the self are mixed and require clarification. Extending previous research, we examined the association between generalized authoritarianism (GA, indicated by right-wing authoritarianism and social dominance orientation) and subjective well-being (SWB, indicated by positive affect, negative affect, and life satisfaction) by testing simultaneously the general-level association between GA and SWB as well as specific residual associations between GA and SWB components, independent of basic personality dimensions. We observed a significant general-level association between GA and SWB whereby heightened authoritarianism predicted greater SWB. No residual associations were found between specific GA and SWB components. Despite being “bad” for others, generalized authoritarianism may be “good” for the self.     

AN EVALUATION OF A PROGRESSIVE HIGH-PROBABILITY INSTRUCTIONAL SEQUENCE COMBINED WITH LOW-PROBABILITY DEMAND FADING IN THE TREATMENT OF FOOD SELECTIVITY

Few studies have examined the effects of the high‐probability instructional sequence in the treatment of food selectivity, and results of these studies have been mixed (e.g., Dawson et al., 2003 ; Patel et al., 2007 ). The present study extended previous research on the high‐probability instructional sequence by combining this procedure with low‐probability demand fading with 2 boys with autism (9 and 10 years old) who had a history of food selectivity and engaged in active food refusal behaviors when presented with novel foods. Response requirements were faded gradually from responses the child would tolerate (e.g., touching the food) to the final requirement of chewing and swallowing the food. The antecedent‐based intervention was implemented in the absence of escape extinction and was effective in increasing food consumption for both participants. Possible mechanisms responsible for the effectiveness of the intervention are discussed along with directions for future research.     

Evaluation of subclinical depression in children using self-, peer-, and teacher-report measures

This study reports on several classification issues utilizing the Children's Depression Inventory (CDI), the Child Behavior Checklist-Teacher Form (CBCL-T), and the Peer Nomination Inventory of Depression (PNID). The first sample contained 752 public school children in grades 5, 6, and 9. A second sample of 142 fifth-graders was included to have an additional PNID comparison group. Results revealed moderate correlations between the CDI and the CBCL-T and PNID. Use of multiple criteria for selecting children as depressed was discussed, and selection rates using multiple measures with either strict or lenient cutoff scores were given. Normative data on the PNID were evaluated, and it was suggested that norms for the PNID may not be generalizable to other samples. Finally, race and gender analyses showed that CDI scores for females were significantly higher than for males, whereas CDI scores for Hispanics were significantly higher than for non-Hispanic whites. However, Omega-squared analyses for these two variables showed this to be of little practical significance.     

SENSORY EXTINCTION AND SENSORY REINFORCEMENT PRINCIPLES FOR PROGRAMMING MULTIPLE ADAPTIVE BEHAVIOR CHANGE

The role of sensory reinforcement was examined in programming multiple treatment gains in self-stimulation and spontaneous play for developmentally disabled children. Two phases were planned. First, we attempted to identify reinforcers maintaining self-stimulation. Sensory Extinction procedures were implemented in which auditory, proprioceptive, or visual sensory consequences of self-stimulatory behavior were systematically removed and reintroduced in a reversal design. When self-stimulation was decreased or eliminated as a result of removing one of these sensory consequences, the functional sensory consequence was designated as a child's preferred sensory reinforcer. In Phase 2, we assessed whether children would play selectively with toys producing the preferred kind of sensory stimulation. The results showed the following. (1) Self-stimulatory behavior was found to be maintained by sensory reinforcement. When the sensory reinforcer was removed, self-stimulation extinguished. (2) The sensory reinforcers identified for self-stimulatory behavior also served as reinforcers for new, appropriate toy play. (3) The multiple treatment gains observed appeared to be relatively durable in the absence of external reinforcers for play or restraints on self-stimulation. These results illustrate one instance in which multiple behavior change may be programmed in a predictable, lawful fashion by using “natural communities of sensory reinforcement.”     

The use of an ultrasonic monitor for recording locomotor activity

An ultrasonic activity monitor has been designed that can be used to detect motion in air or within an aquarium. Stability and linearity of response of the monitor have been measured. The system has been used to examine activity rhythms of the marine invertebrate,Octoput ornatus Gould.     

INFANT ATTACHMENT SECURITY AND AFFECTIVE-COGNITIVE INFORMATION PROCESSING AT AGE 3

Abstract— Three-year old's attention toward and memory of affectively laden information presented in specialty designed puppet snows were examined to test the hypothesis, based on Bowlby's theory of attachment and the internal-working-model construct central to the theory, that children with secure attachment histories (measured at 12 months) would prove less distractable during positive than negative events and would remember positive events more accurately than negative events, with the reverse being true of children with insecure attachment histories Support for this hypothesis emerged in the case of memory but not attention (for which no attachment effects emerged), even when infants' temperament-emotionality and general verbal intelligence were taken into consideration Results are discussed in terms of life-course implications of affective-cognitive information processing and directions for future research.     

An Investigation of the Discourses Children Draw on Their Constructions of Gender

The mechanisms behind children's constructions of gender are examined in an attempt to identify the various narratives that children draw on. The ways in which these narratives are used in children's talk about gender are analyzed in order to provide a greater understanding of discursive resources available to children. The different types of discourse evident in children's discussion of gender are listed. The discursive contradictions in children's speech and discursive resistance to the construction of gender dichotomy are examined. It is concluded that the children in the sample drew on a wide variety of gender discourses, suggesting that they have a more developed understanding of gender issues than has been recognized previously. Finally, the paper considers the possible methods for deconstruction of dominant gender discourses.     

Medial prefrontal cortex infusions of bupivacaine or AP-5 block extinction of amphetamine conditioned place preference

The present experiments used reversible lesion techniques and intra-mPFC infusions of the n-methyl d-aspartate (NMDA) receptor antagonist d,l-2-amino-5-phosphonovaleric acid (AP-5) to examine the role of the mPFC in extinction of an amphetamine conditioned place preference (CPP). Following initial training and testing for an amphetamine (2 mg/kg) CPP, adult male Long–Evans rats were given extinction trials that were identical to training, except in the absence of peripheral amphetamine injections. Immediately prior to each extinction trial, rats received intra-mPFC infusions of the anesthetic drug bupivacaine (0.75% solution/0.5 μl), AP-5 (1.25, 2.5, 5.0 μg/0.5 μl), or saline. Following extinction training, rats were given a second CPP test session. Rats receiving intra-mPFC infusions of saline displayed extinction of CPP behavior. In contrast, intra-mPFC infusions of bupivacaine or AP-5 (2.5, 5.0 μg) blocked CPP extinction. The findings indicate (1) the mPFC mediates extinction of approach behavior to drug-associated environmental contexts, and (2) NMDA receptor blockade within the mPFC is sufficient to block extinction of amphetamine CPP behavior.     

D-Cycloserine enhances memory consolidation of hippocampus-dependent latent extinction

Adult male Long-Evans rats were trained to run in a straight-alley maze for food reward and subsequently received hippocampus-dependent latent extinction training. Immediately following latent extinction, rats received peripheral injections of the NMDA receptor partial agonist D-cycloserine (DCS, 15 mg/kg), or saline. Twenty-four hours later, rats received four extinction "probe" trials. Relative to saline controls, latencies to reach the goal box on probe trials were significantly higher in rats that had received DCS. These findings indicate that memory consolidation underlying hippocampus-dependent latent extinction, a cognitive form of learning in which the previously rewarded response is not made during extinction training, can be enhanced by NMDA-receptor agonism.     

The Effects of Weight Loss Attempts, Exercise Initiation, and Dietary Practices on Health Related Quality of Life

This study (N = 98) randomly placed participants in either a higher protein or American Heart Association diet group with each group initiating an aerobic exercise program. Body composition (BC) was measured using four different methodologies (DEXA, BIA, skinfold, BMI) along with height and weight, while Health-Related Quality of Life (HRQOL) changes were measured using the Medical Outcomes Short Form 36 (SF-36). There were no significant time/diet interactions in HRQOL scores, body fat measures, and weight with the exception of Role-Physical scores (p = .006) with posttest scores higher in participants in Diet 1. Role-Physical scores changed significantly in participants in Diet 1 (p = .0001) and Diet 2 (p = .026) with higher posttest scores in each group. Social functioning had a significant main effect for time in both groups with pretest scores in both diet groups lower than their respective posttest scores (p = .015). HRQOL pretest scores were not significantly different between groups at baseline (p = .56). ANOVA revealed no significant differences in average calories between groups (p = .88). Analysis revealed no differences in exercise in minutes (p = .66) nor statistically significant changes in BC or weight (p = .65). Conclusions: Improvements in HRQOL were demonstrated in two subscales related to physiological and psychological functioning. These novel findings add to literature suggesting that HRQOL, at least concerning social functioning, work and other daily activities (Role-Physical) may improve by initiating an exercise and dietary program even when weight loss or BC improvements have been unsuccessful.
