Neuropsychological impairments in the syndromes of schizophrenia: a comparison between different dimensional models

This study investigates the associations between the different symptom dimensions of schizophrenia and neuropsychological performances. Globally, the results replicate previously described associations. The "negative" dimension correlates with impaired sustained attention and working memory, thus suggestive of dorsolateral frontal cortex dysfunction. "Disorganization" correlates with the ability to inhibit proactive interference. thus with ventromedial frontal dysfunction. The results also add support to the view that the "psychotic" dimension described in three-dimension models includes in fact two distinct dimensions, (1) "hallucinations," here associated to episodic memory measures, and (2) "delusions", here associated to visuospatial attention, thus suggestive of mediotemporal and posterior neocortical dysfunction, respectively.     

A model of union participation: the impact of perceived union support, union instrumentality, and union loyalty

Perceived union support and union instrumentality have been shown to uniquely predict union loyalty. This study was the first to explicitly examine the relation between perceived union support and union instrumentality. Surveys were completed by 273 union members and 29 union stewards. A comparison of 2 models, 1 based on organizational support theory and 1 based on union participation theories, found that the model based on organizational support theory, in which union instrumentality was an antecedent to perceived union support and led to union loyalty and subsequently union participation, best fit the data. The model based on union participation theories, in which perceived union support was an antecedent of union instrumentality and led to union loyalty and subsequently union participation, was not supported. Union instrumentality was related to union commitment, but the relation was completely mediated by perceived union support.     

A comparison of song-lyric and prose self-instruction procedures for increasing novel skills in children

We compared the effects of the effects of self-instructions in the form of prose or song lyrics in the acquisition of gross motor tasks in 4 third-grade children. We taught participants 4 pairs of gross motor tasks, with one task in each pair taught with prose self-instructions and the other taught with song lyric self-instructions. Both self-instruction procedures were effective for teaching tasks; however, acquisition was quicker with song lyric self-instruction for 4 task pairs, acquisition was quicker with prose self-instruction for 3 task pairs; and similar for 1 task pair. Participants were then able to select their preferred method of self-instruction for a novel, applied skill. Two participants selected song-lyric self-instructions and 2 participants selected prose self-instructions.     

Secular or nonreligious? Investigating and interpreting generic ‘not religious’ categories and populations

In research dealing with religious affiliation, generic nonreligious categories – ‘no religion’, ‘not religious’, ‘nonreligious’, ‘nones’ – are frequently used to measure secularity and secularisation processes. Analysis of these categories is, however, problematic because they have not received dedicated methodological attention. Using qualitative research conducted in the UK, this article investigates what nonreligious categories measure and, specifically, whether they indicate non-identification or disaffiliation as assumed or an alternative form of cultural affiliation. Findings suggest that generic nonreligious categories are sometimes used to express substantive positions and public identities, and that these are diverse. These findings flatten distinctions between religious and nonreligious categories as ‘positive’ and ‘negative’ respectively and indicate problems therefore in using nonreligious identification to measure secularity and secularisation. They suggest nonreligious identification is, however, a useful indicator of the advance of nonreligious cultures and the ‘nonreligionisation’ of societies.
