Randomized clinical trial of adapted mindfulness-based stress reduction versus group cognitive behavioral therapy for heterogeneous anxiety disorders

ObjectiveTo compare a mindfulness-based intervention with cognitive behavioral therapy (CBT) for the group treatment of anxiety disorders.MethodOne hundred five veterans (83% male, mean age = 46 years, 30% minority) with one or more DSM-IV anxiety disorders began group treatment following randomization to adapted mindfulness-based stress reduction (MBSR) or CBT.ResultsBoth groups showed large and equivalent improvements on principal disorder severity thru 3-month follow up (ps < .001, d = ?4.08 for adapted MBSR; d = ?3.52 for CBT). CBT outperformed adapted MBSR on anxious arousal outcomes at follow up (p < .01, d = .49) whereas adapted MBSR reduced worry at a greater rate than CBT (p < .05, d = .64) and resulted in greater reduction of comorbid emotional disorders (p < .05, d = .49). The adapted MBSR group evidenced greater mood disorders and worry at Pre, however. Groups showed equivalent treatment credibility, therapist adherence and competency, and reliable improvement.ConclusionsCBT and adapted MBSR were both effective at reducing principal diagnosis severity and somewhat effective at reducing self-reported anxiety symptoms within a complex sample. CBT was more effective at reducing anxious arousal, whereas adapted MBSR may be more effective at reducing worry and comorbid disorders.     

Infants' reasoning about opaque and transparent occluders in an individuation task

There has been some debate about whether infants 10 months and younger can use featural information to individuate objects. The present research tested the hypothesis that negative results obtained with younger infants reflect limitations in information processing capacities rather than the inability to individuate objects based on featural differences. Infants aged 9.5 months saw one object (i.e. a ball) or two objects (i.e. a box and a ball) emerge successively to opposite sides of an opaque occluder. Infants then saw a single ball either behind a transparent occluder or without an occluder. Only the infants who saw the ball behind the transparent occluder correctly judged that the one-ball display was inconsistent with the box-ball sequence. These results suggest that: (a) infants categorize events involving opaque and transparent occluders as the same kind of physical situation (i.e. occlusion) and (b) support the notion that infants are more likely to give evidence of object individuation when they need to reason about one kind of event (i.e. occlusion) than when they must retrieve and compare categorically distinct events (i.e. occlusion and no-occlusion).     

Involvement of alpha-bungarotoxin-sensitive nicotinic receptors in long-term memory formation in the honeybee (Apis mellifera)

In the honeybee Apis mellifera, multiple-trial olfactory conditioning of the proboscis extension response specifically leads to long-term memory (LTM) which can be retrieved more than 24 h after learning. We studied the involvement of nicotinic acetylcholine receptors in the establishment of LTM by injecting the nicotinic antagonists mecamylamine (1 mM), alpha-bungarotoxin (alpha-BGT, 0.1 mM) or methyllycaconitine (MLA, 0.1 mM) into the brain through the median ocellus 20 min before or 20 min after multiple-trial learning. The retention tests were performed 1, 3, and 24 h after learning. Pre-training injections of mecamylamine induced a lower performance during conditioning but had no effect on LTM formation. Post-training injections of mecamylamine did not affect honeybees' performances. Pre-training injections of MLA or post-training injection of alpha-BGT specifically induced LTM impairment whereas acquisition as well as memory retrieval tested 1 or 3 h after learning was normal. This indicates that brain injections of alpha-BGT and MLA did not interfere with learning or medium-term memory. Rather, these blockers affect the LTM. To explain these results, we advance the hypothesis that honeybee alpha-BGT-sensitive acetylcholine receptors are also sensitive to MLA. These receptors could be essential for triggering intracellular mechanisms involved in LTM. By contrast, medium-term memory is not dependent upon these receptors but is affected by mecamylamine.     

Exploring a recognition-induced recognition decrement

Four experiments were performed to explore a recognition decrement that is associated with the recognition of a word from a short list. The stimulus material for demonstrating the phenomenon was a list of words of different syntactic types. A word from the list was recognized less well following a decision that a word of the same type had occurred in the list than following a decision that such a word had not occurred in the list. A recognition decrement did not occur for a word of a given type following a positive recognition decision to a word of a different type. A recognition decrement did not occur when the list consisted exclusively of nouns. It was concluded that the phenomenon may reflect a criterion shift but, probably, does not reflect a list strength effect, suppression, or familiarity attribution consequent to a perceived discrepancy between actual and expected fluency.     

Psychometric properties of the Trauma Stages of Recovery

Of the trauma theories available, Herman's has captured the essential features common to most traumatic etiologies. Continued development of this theory has included dimensions within stages of recovery. The Trauma States of Recovery is presented here as a way of assessing stages of recovery and inherent components. Three samples of about 500 college students each and a clinical sample (n=34) were recruited. Independent principal components analyses, employing a scree plot, gave a five-component solution accounting for 40.2% of the total variance. The component solution employed Promax rotation for the correlated components. The five components were named Emotional Awareness and Control, Symptom Mastery, Coping, Memory, and Relationships. Internal consistencies, test-retest reliability, and split-half reliability were acceptable. Response bias was low. Convergent validity (with various subscales from the Beck Depression Inventory, the Self-esteem Scale, the Spielberger Anger-Expression Scale, and the Dissociative Experiences Scale) and discriminant validity (with various subscales of the AIDS Knowledge and Attitudes Survey and Jackson's Personality Research Form Dominance Scale) were promising. The Trauma Stages of Recovery also significantly discriminated between clinical and nonclinical samples on three of the five components, Symptom Mastery, Coping, and Memory.     

Development of the comprehension and appreciation of fables

The authors proposed and tested a model of fable comprehension and appreciation. They proposed that fables are metaphoric in that they teach moral lessons about human activity, and that apprehension of the moral derives from a belief in a just world. In Study 1, children from kindergarten to 8th grade and college students received Aesop fables, reversed-outcome Aesop fables, and fable-like stories. As predicted, kindergartners and some 1st graders did not demonstrate a belief in a just world and did not differentiate between normal and reversed-outcome Aesop fables. Quality of morals provided by older participants was superior to that of younger participants. In Study 2, the quality of fable moral was found to be significantly correlated with quality of proverb and metaphor interpretation. Also, memory for goal or intention story elements was found to be related to quality of moral produced. Directions for future research are identified.     

Parent-Child Symbolic Pay: Three Theories in Search of an Effect

In symbolic play, children construct increasingly sophisticated representations of the world as well as relations between symbols and their external referents as they advance upon their developing cognitions about people, actions, and objects. Presumably, more sophisticated partners, like parents, promote children′s development in this domain. Yet the empirical literature to date shows little support for the notion that child solitary symbolic play grows through adult-child symbolic play interactions. This paper first reviews empirical studies that address the role and effects of a more sophisticated partner on children′s early symbolic play. Next, the paper presents three theoretical perspectives that support a view that symbolic play and advance children′s representational competencies more broadly; they include attachment, scaffolding, and ethological theory. Finally, the paper revisits the literature on interactive influences on children′s play reconsidering the nature and role of specific independent and dependent variables in studies of the growth of children′s symbolic play.     

Stakes and risk: Incapacitative intent in sentencing decisions

Measures of seriousness of the conviction offense and prior criminal record are strong correlates of sentences. This is consistent with a desert orientation to sentencing. Competing sentencing theories emphasize concepts of risk and incapacitation, but their roles in sentencing decisions have received less attention. This study focused on judicial risk assessments and on the concept of stakes. Both variables plausibly are related to incapacitative intents of judges. Our hypotheses that the risk and stakes measures used are relatively independent and correlated with, and have an interaction effect on, decision outcomes were supported. Both judges' assessments of risk and our stakes scale accounted for substantial variation in the decision to incarcerate. Time actually served in confinement also was related substantially to stakes, risk, and their interaction. Implications of the stakes and risk concepts for future guidelines development and decision study in criminal justice are discussed.     

Sex differences in the preferences for specific female body shapes

The purpose of this study was to examine the somatic preferences of males and females for detailed anatomical drawings of female stimulus figures to examine their ability to predict the preferences for members of the opposite sex. The figures were systematically varied on three dimensions (bust, waist, and hips), with three sizes of each (small, medium, and large). The 12 figures were rated by 100 male and female subjects on a 7-point bipolar construct scale, ranging from extremely attractive to extremely unattractive. This was done both for the subjects' personal perceptions and for their predicted ratings of the opposite sex. Multivariate and univariate analyses yielded several sex, rating-perceptive (self vs. other), figure shape differences and interactions. Male subjects displayed a preference for large busts and hourglass shapes, which are accurately predicted by the females. Males predicted that females would rate slimmer figure highly, and females predicted that males would rate larger figures highly. The results are considered in light of related research in this area.
