Binding, relational memory, and recall of naturalistic events: a developmental perspective

This research was an investigation of children's performance on a task that requires memory binding. In Experiments 1 and 2, 4-year-olds, 6-year-olds, and adults viewed complex pictures and were tested on memory for isolated parts in the pictures and on the part combinations (combination condition). The results suggested improvement in memory for the combinations between the ages of 4 and 6 years but not in memory for the isolated parts. In Experiments 2 and 3, the authors also examined the developmental relationship between performance in the combination condition and free recall of a naturalistic event, finding preliminary evidence that performance on a memory task that requires binding is positively related to performance in episodic memory.     

White-matter microstructure and language lateralization in left-handers: A whole-brain MRI analysis

Most people are left-hemisphere dominant for language. However the neuroanatomy of language lateralization is not fully understood. By combining functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), we studied whether language lateralization is associated with cerebral white-matter (WM) microstructure. Sixteen healthy, left-handed women aged 20–25 were included in the study. Left-handers were targeted in order to increase the chances of involving subjects with atypical language lateralization. Language lateralization was determined by fMRI using a verbal fluency paradigm. Tract-based spatial statistics analysis of DTI data was applied to test for WM microstructural correlates of language lateralization across the whole brain. Fractional anisotropy and mean diffusivity were used as indicators of WM microstructural organization. Right-hemispheric language dominance was associated with reduced microstructural integrity of the left superior longitudinal fasciculus and left-sided parietal lobe WM. In left-handed women, reduced integrity of the left-sided language related tracts may be closely linked to the development of right hemispheric language dominance. Our results may offer new insights into language lateralization and structure–function relationships in human language system.     

Grounding and the argument from explanatoriness

In recent years, metaphysics has undergone what some describe as a revolution: it has become standard to understand a vast array of questions as questions about grounding, a metaphysical notion of determination. Why should we believe in grounding, though? Supporters of the revolution often gesture at what I call the Argument from Explanatoriness: the notion of grounding is somehow indispensable to a metaphysical type of explanation. I challenge this argument and along the way develop a “reactionary” view, according to which there is no interesting sense in which the notion of grounding is explanatorily indispensable. I begin with a distinction between two conceptions of grounding, a distinction which extant critiques of the revolution have usually failed to take into consideration: grounding qua that which underlies metaphysical explanation and grounding qua metaphysical explanation itself. Accordingly, I distinguish between two versions of the Argument from Explanatoriness: the Unexplained Explanations Version for the first conception of grounding, and the Expressive Power Version for the second. The paper’s conclusion is that no version of the Argument from Explanatoriness is successful.     

Coding of on-line and pre-planned movement sequences

Recent experiments have demonstrated that complex multi-element movement sequences were coded in visual-spatial coordinates even after extensive practice, while relatively simple spatial-temporal movement sequences are coded in motor coordinates after a single practice session. The purpose of the present experiment was to determine if the control process rather than the difficulty of the sequence played a role in determining the pattern of effector transfer. To accomplish this, different concurrent feedback conditions were provided to two groups of participants during practice of the same movement sequence. The results indicated that when concurrent visual feedback was provided during the production of the movement, which was thought to encourage on-line control, the participants performed transfer tests with the contra-lateral limb better when the visual-spatial coordinates were reinstated than when the motor coordinates were reinstated. When concurrent visual feedback was not provided, which was thought to encourage pre-planned control, the opposite was observed. The data are consistent with the hypothesis that the mode of control dictates the coordinate system used to code the movement sequence rather than sequence difficulty or stage of practice as has been proposed.     

Maslow and Miller: An Exploration of Gender and Affiliation in the Journey to Competence

This article shows that although neither Abraham Maslow nor Jean Baker Miller reference each other in their writings, they are following different paths to the same conclusion: competence proceeds from connection. Miller and Maslow both describe a developmental model that applies equally to women and men. The conclusion of the authors of this article is that there is no need for separate developmental models for men and women because all self‐actualization and optimum mental health evolves from affiliation.     

Validation of the shortened cope for use with breast cancer patients undergoing radiation therapy

To study the relationship between cancer and emotional adjustment, investigation of situation-specific coping behaviors with respect to narrowly defined Stressors has recently been promoted. The development and validation of shorter instruments, designed to facilitate completion by clinical populations, has also been recommended. The current study examined the coping skills used by French-Canadian women undergoing radiation therapy for breast cancer. A factor analysis of the 28-item shortened COPE (Carver, Scheier, & Weintraub, 1989) yielded the following eight factors: disengagement, self-distraction, active coping, using emotional support from husband/ partner, using emotional support from friends, turning to religion, humor, and substance use. The test-retest and Cronbach alpha internal consistency reliability coefficients of the French-Canadian shortened COPE were actually higher than those observed in the full-length version of the instrument. In addition, the eight factor-based scores correlated in a theoretically meaningful manner with existing measures of coping skills with illness (Coping with Health Injuries and Problems; CHIP) and mood disturbance (Profile of Mood States; POMS), thus suggesting good construct convergent and concurrent criterion validity. In particular, the disengagement COPE scale was correlated highly with anxiety, depression, and anger. While further validation is recommended, the results show promise for the shortened COPE in assessing coping in women with breast cancer, and also provide continued evidence for the notion that specific coping skills are associated with particular mood states.     

Relationship of Prosody Perception to Personality and Aggression

One-hundred-fifteen participants (73 female, 42 male) were evaluated for prosody, or vocal emotion, perception, personality factors, relational aggression and physical aggression. The male participants reported higher levels of physical aggression, and the female participants reported greater Neuroticism, consistent with other data. For the male participants, better perception of prosody was related to both greater Extraversion and greater Conscientiousness, all involved in interpersonal functioning. These relationships were not found in the female participants, but there was a relationship between perception of prosody and relational aggression. Women who were better at perceiving the emotional status of others based on vocal cues were less relationally aggressive. Perhaps greater relational aggression reflects a poor adaptation to diminished ability to perceive emotional status.     

Is there a link between irritable bowel syndrome and left-handedness?: An exploratory study

Recent research has found that people with Irritable Bowel Syndrome (IBS) and those with Inflammatory Bowel Disease (IBD) show a relative deficit in verbal IQ, compared to their own performance IQ, and the IQ of a healthy comparison group. It has been suggested that the elevated prevalence of left-handedness shown in previous studies investigating people with IBD is due to compromised left-hemisphere development. This may be associated with a decrement in certain cognitive functions such as verbal IQ. A shift in brain dominance from left to right has been found in many atopic and immunological diseases as well as in autonomic dysfunctions. It was uncertain whether this would apply to people with IBS, a functional disorder in which the cause or causes remain unclear. Therefore, the aim of this preliminary study was to investigate whether people with IBS have an increased prevalence of left-handedness. It was found that there was an association between IBS and left-handedness, showing that further research on this association both in IBS and other functional disorders (as well as on the similarities between IBS and IBD) is warranted.
