Improving Written Argumentative Synthesis by Teaching the Integration of Conflicting Information from Multiple Sources

The goal of this study was to assess the effectiveness of 2 different types of intervention aimed at improving written argumentative synthesis by integrating conflicting information from different sources. Both interventions combined the use of a guide with collaborative practice, but one of them also included explicit strategy instruction. Only students who received additional explicit instruction showed an improved ability to integrate conflicting information and increased the number of arguments they selected from the sources.     

Longitudinal Relationships Between Positive Affect,Loneliness, and Suicide Ideation: Age‐Specific Factors in a General Population

The aims of this study were to analyze whether positive and negative affect, social support, and loneliness are factors longitudinally related to suicide ideation in the general population in different age groups. A total of 2,392 individuals from a nationally representative sample of the Spanish general population were evaluated in 2011–2012 and in 2014–2015. After including relevant control variables in the analyses, lower positive affect was prospectively related to ideation in 18‐ to 59‐year‐old individuals, whereas feelings of loneliness were related to ideation in 60‐year‐and‐older individuals. Social support was not associated with suicide ideation in any age group. These results are in line with the need for age‐tailored suicide prevention programs. The present findings might also suggest that health care professionals should consider feelings of loneliness rather than social support to assess the presence of suicide ideation in older people.     

Motivational versus volitional mediation of passivity in institutionalized older people

The relationship between perceived loss of control and passivity in social activities in a non-handicapped institutionalized elderly population was assessed. Perceived loss of control was assessed from three different types of expectancies: low action-outcome expectancies, high situation-outcome expectancies, and low efficacy expectancies. Passivity scores were reported by the staff. The effect of these three types of expectancies on passivity was analyzed in terms of motivation and volition, which were treated as mediating variables. Overall analysis of the structural equations, as well as partial hierarchical regression analyses, showed that efficacy expectancies were good predictors of passivity, but this was not the case for the action-outcome and situation-outcome expectancies. These results lend more support to a volitional rather than to a motivational interpretation of the effect of control on passivity. The implications of these results for intervention and for a differentiated conception of expectancies are discussed.     

A multiple‐stimulus‐without‐replacement assessment for sexual partners: Purchase task validation

The current study developed and tested a multiple‐stimulus‐without‐replacement (MSWO) assessment for potential sexual partners for use in research on human immunodeficiency virus. College students (N = 41) first completed an MSWO assessment and then completed a hypothetical purchase task for encounters with partners identified by the MSWO as high, median, and low preference. Overall, hypothetical purchase task responding was consistent with that from the MSWO, in that the highest valuation was observed for the high‐preference partner and the lowest for the low‐preference partner. Potentially interesting individual differences in purchase task responding, however, were obtained; some subjects showed differentiated responding among the 3 preference levels (n = 15), whereas others similarly valued high‐ and median‐preference partners (n = 5), and others similarly valued low‐ and median‐preference partners (n = 18).
