Couple-responsible therapy process: positive proximal outcomes

Therapist-couple struggle vs. cooperation is linked to clinical outcome. This research conceptualizes and investigates treatment process as it relates to the occurrence of struggle versus cooperation. Models of couple-responsible and therapist-responsible process in couple therapy were developed. Couple-responsible process consists of enactments, accommodation, and inductive process. Therapist-responsible process consists of primary therapist-couple interaction, therapist interpretation, and direct instruction. In counterbalanced order, 25 couples were exposed to couple-responsible and therapist-responsible episodes during one therapy session. Couples reviewed videotapes of the episodes and completed measures of responsibility, struggle, and cooperation. Perceived responsibility was higher and struggle was lower during couple-responsible episodes. No difference in cooperation was found. Presence or absence of a contrast condition, where couples reported on one therapist process after already experiencing its opposite, led to main effects for responsibility and struggle, and mediated effects of struggle and cooperation. Generally speaking, responsibility was even higher during couple-responsible episodes and even lower during therapist-responsible episodes when contrast was present. Similarly, struggle was even lower during couple-responsible episodes and even higher during therapist-responsible episodes when contrast was present. For both couple-responsible and therapist-responsible episodes, cooperation was negatively affected by a shift from the prior, opposite therapist process. Significant proportions of the variance in responsibility, struggle, and cooperation, however, were not accounted for by therapist process alone.     

Appetitive behavior, compulsivity, and neurochemistry in Prader-Willi syndrome

Advances in genetic research have led to an increased understanding of genotype-phenotype relationships. Excessive eating and weight gain characteristic of Prader-Willi syndrome (PWS) have been the understandable focus of much of the research. The intense preoccupation with food, lack of satiation, and incessant food seeking are among the most striking features of PWS. It has become increasingly clear that the behavioral phenotype of PWS also includes symptoms similar to obsessive compulsive disorder, which in all probability interact with the incessant hunger and lack of satiation to engender the intense preoccupation and food seeking behavior that is characteristic of this disorder. Several lines of evidence suggest that genetic material on chromosome 15 may alter synthesis, release, metabolism, binding, intrinsic activity, or reuptake of specific neurotransmitters, or alter the receptor numbers and/or distribution involved in modulating feeding. Among the likely candidates are GABAnergic, serotonergic, and neuropeptidergic mechanisms. This review summarizes what is known about the appetitive behavior and compulsivity in PWS and discusses the possible mechanisms underlying these behaviors.

Gender differences in responses to depressed mood in a college sample

Two studies tested the hypothesis that women are more likely than men to focus on themselves and their mood when in a depressed mood, and that this leads them to experience longer periods of depressed mood. In both studies subjects were predominantly Caucasian college students. In our first study, a laboratory study, females chose to engage in an emotion-related task significantly more often than did males, even when this lead them to focus on an existing sad mood. In the second study, a prospective naturalistic study, females were more likely than males to evince an emotion-focused ruminative style of coping with their moods. A ruminative response style at Time 1 was a significant predictor of depression scores at Time 2, even after initial levels of depressed mood were taken into account. Furthermore, once rumination levels were controlled for, gender was no longer a potent predictor of depression outcome. The implications of these response styles for treatment are discussed.We thank Brandi Battistoni, Kim Bergquist, Rachel Carr, Lisa Lougee, and especially Ariel Lang for their invaluable help in data collection.

The Effects of Gender on Career Decision Problems in Young Adults

The authors investigated gender differences in psychological problems in the career decision making (CDM) process of young adults. Specifically, problems with decision anxiety, life-goal awareness, luck-fate orientation, authority orientation, and secondary gain motivation were investigated. Methodology involved administering the Career Decision Diagnostic Assessment (CDDA) instrument to 1,006 college students from four universities. Results indicated no gender differences in global levels of problems in CDM. Women reported more problems with life-goal awareness and authority orientation than did men. Men reported more problems with secondary gain motivations than did women. The results are discussed in terms of implications for gender-differentiated career counseling.     

Expectancies of reinforcer location and quality as cues for a conditional discrimination in pigeons

Experiment 1 demonstrated that reliably correlating different reinforcer locations (top vs. bottom) with sample stimuli markedly enhanced the performance of White Carneaux pigeons in a spatial conditional discrimination. This differential outcome effect was more evident at longer retention intervals. In Experiment 2, pigeons were given the opportunity to learn about two redundant reinforcer features--location (top vs. bottom) and quality (grain vs. chow). Which reinforcer feature exerted control over choosing depended on task structure. In the congruent task, where pecks to the top key operated the top feeder and pecks to the bottom key operated the bottom feeder, reinforcer location exerted predominant control. In the incongruent task, where pecks to the top key operated the bottom feeder and vice versa, reinforcer quality exerted exclusive control. These results have implications for the nature of reinforcer representations in instrumental learning.     

Recall norms of common spaces and activities of college students

To collect normative data on familiar spaces and behaviors of college students, two recall tasks were performed. In Experiment 1, 219 undergraduates recalled spaces where they spend time. In Experiment 2,155 undergraduates recalled the kinds of activities they do in familiar spaces. The norms provided here include 40 spaces and 123 different behaviors. Gender differences and transituational behaviors are also reported.     

When do letter features migrate? A boundary condition for feature-integration theory

Feature-integration theory postulates that a lapse of attention will allow letter features to change position and to recombine as illusory conjunctions (Treisman & Paterson, 1984). To study such errors, we used a set of uppercase letters known to yield illusory conjunctions in each of three tasks. The first, a bar-probe task, showed whole-character mislocations but not errors based on feature migration and recombination. The second, a two-alternative forced-choice detection task, allowed subjects to focus on the presence or absence of subletter features and showed illusory conjunctions based on feature migration and recombination. The third was also a two-alternative forced-choice detection task, but we manipulated the subjects' knowledge of the shape of the stimuli: In the case-certain condition, the stimuli were always in uppercase, but in the case-uncertain condition, the stimuli could appear in either upper- or lowercase. Subjects in the case-certain condition produced illusory conjunctions based on feature recombination, whereas subjects in the case-uncertain condition did not. The results suggest that when subjects can view the stimuli as feature groups, letter features regroup as illusory conjunctions; when subjects encode the stimuli as letters, whole items may be mislocated, but subletter features are not. Thus, illusory conjunctions reflect the subject's processing strategy, rather than the architecture of the visual system.     

Categories by which we try to live

Categories We Live By makes several claims about Judith Butler's Gender Trouble which Butler seeks to contest, while remaining in fundamental agreement with most of the conclusions in Asta Sveinsdottir's book. At issue is whether or not performativity can rightly be restricted to what is called an exercitive in J. L. Austin's sense, whether Butler is a radical constructivist or a qualified one, and whether unauthorized speech acts have a power to bring a reality into being that is different from those authorized by legal regimes. Along the way, Butler suggest that establishing facts takes place within variable historical schemes and that this argument is neither a denial or facts nor of materiality. Finally, an individualist idea of freedom is subject to criticism in order to make way for an historically constrained freedom, collective in nature.     

Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks

Inattentional blindness is described as the failure to perceive a supra-threshold stimulus when attention is directed away from that stimulus. Based on performance on an explicit recognition memory test and concurrent functional imaging data Rees, Russell, Frith, and Driver [Rees, G., Russell, C., Frith, C. D., & Driver, J. (1999). Inattentional blindness versus inattentional amnesia for fixated but ignored words. Science, 286, 2504–2507] reported inattentional blindness for word stimuli that were fixated but ignored. The present study examined both explicit and implicit memory for fixated but ignored words using a selective-attention task in which overlapping picture/word stimuli were presented at fixation. No explicit awareness of the unattended words was apparent on a recognition memory test. Analysis of an implicit memory task, however, indicated that unattended words were perceived at a perceptual level. Thus, the selective-attention task did not result in perfect filtering as suggested by Rees et al. While there was no evidence of conscious perception, subjects were not blind to the implicit perceptual properties of fixated but ignored words.
