Extensive occupational finger use delays age effects in tactileperception—an ERP study

Tactile expertise, resulting from extensive use of hands, has previously been shown to improve tactile perception in blind people and musicians and to be associated with changes in the central processing of tactile information. This study investigated whether expertise, due to precise and deliberate use of the fingers at work, relates to improved tactile perception and whether this expertise interacts with age. A tactile pattern and a frequency discrimination task were conducted while ERPs were measured in experts and nonexperts of two age groups within middle adulthood. Independently of age, accuracy was better in experts than in nonexperts in both tasks. Somatosensory N70 amplitudes were larger with increasing age and for experts than for nonexperts. P100 amplitudes were smaller in experts than in nonexperts in the frequency discrimination task. In the pattern discrimination task, P300 difference wave amplitude was reduced in experts and late middle-aged adults. In the frequency discrimination task, P300 was more equally distributed in late middle-aged adults. We conclude that extensive, dexterous manual work leads to acquisition of tactile expertise and that this expertise might delay, but not counteract, age effects on tactile perception. Comparable neurophysiological changes induced by age and expertise presumably have different underlying mechanisms. Enlarged somatosensory N70 amplitudes might result from reduced inhibition in older adults but from enhanced, specific excitability of the somatosensory cortex in experts. Regarding P300, smaller amplitudes might indicate fewer available resources in older adults and, by contrast, a reduced need to engage as much cognitive effort to the task in experts.     

Language use of depressed and depression-vulnerable college students

Essays written by currently-depressed, formerly-depressed, and never-depressed college students were examined for differences in language that might shed light on the cognitive operations associated with depression and depression-vulnerability. A text analysis program computed the incidence of words in predesignated categories. Consistent with Beck's cognitive model and with Pyczsinski and Greenberg's self-focus model of depression, depressed participants used more negatively valenced words and used the word, "I" more than did never-depressed participants. Formerly-depressed (presumably depression-vulnerable) participants did not differ from never-depressed participants on these indices of depressive processing. However, consistent with prediction, formerly-depressed participants' use of the word "I" increased across the essays and was significantly greater than that of never-depressed writers in the final portion of the essays.     

The ecological validity of the autonomic-subjective response dissociation in repressive coping

Background and Objectives: Repressive coping has been associated with elevated cardiovascular reactivity and diminished self-reported negative affect (so-called autonomic-subjective response dissociation, ASRD) in response to laboratory stressors. However, there is a lack of knowledge regarding the ecological validity of this response pattern. Design: An ambulatory assessment strategy was applied in order to analyze associations between ASRD and repressive coping throughout a day. Methods: A sample of 114 individuals was recruited. Heart rate was recorded via ECG and subjective reports of negative affect as well as the experience of demand and control (as indicators of stress) and situational characteristics were assessed several times a day via mobile electronic devices. Results: Repressive coping relative to other coping dispositions was accompanied by elevated ASRD during stressful episodes in daily life, thus supporting previous laboratory research. Conclusions: The findings suggest that repressive coping is associated with a discrepancy between subjective reports of negative affect and autonomic responding to stressful encounters in everyday life, which might impact health.     

A critique of Plantinga's theological foundationalism

Conclusion I think that the epistemological theory presented by Plantinga would be more plausible if it were amended in a way that would be consistent with the no-foundations view suggested above. We have considered in detail his conception of basic beliefs in Section II above, and noted that his conception of basicality was obscure. For Plantinga, beliefs are basic only under certain conditions, and this is an obscure notion of basicality because unlike basic beliefs in a more traditional foundationalist theory, there is no incorrigibility at the foundation, with no suitable substitute. Consequently, a foundationalist like Plantinga is faced with the same problem he thinks is inherent in coherentism; namely, how warrant for the noetic structure is guaranteed.In fact, it is unclear how Plantinga's version of foundationalism differs significantly from Williams' no-foundations view. If the noetic structure is potentially unlimited in the way that I have suggested, one could have a temporally local foundationalism which is consistent with Williams' no-foundations view, for all of Williams' arguments attack the notion of ultimate warrant for the noetic structure. And if, at a given time, a person takes certain beliefs in their noetic structure as basic contingent upon subsequent assessment of those beliefs, we have something very much like Plantinga's foundationalism. Such beliefs would be basic in the sense of being non-inferentially credible, but this would not entail their functioning as grounds for the noetic structure as a whole, for the element lacking in this no-foundations view is the certain sort of experience which Plantinga thinks is necessary as a ground of the basic belief. But given the problems discussed above concerning criteria for basicality and the consequent problems concerning the identification of what sorts of experience function as a suitable ground, it is unclear in what way Plantinga's position is preferable.Plantinga's fundamental objection to a coherence view of justification was that there is no way of accounting for ultimate warrant for a noetic structure. But in reference to his own theory, Plantinga states that:The justification-conferring conditions mentioned above must be seen as conferring prima facie rather than ultima facie, or all-things-considered justification. This justification can be overridden. (Reason, 83)If, however, basic beliefs are merely prima facie justified and can be overridden, then there is no accounting for ultimate warrant in theological foundationalism either. Basic beliefs in a foundationalist position are supposed to serve the function of providing an end to the process of justification, but they do not serve this function in Plantinga's system. In defending the no-foundations view of justification, Williams recognizes that some beliefs are in fact accepted as non-inferentially credible or that some beliefs happen to be reliable (86, 94). If this is all that basic beliefs amount to, i.e. beliefs that are prima facie credible yet still defeasible, then theological foundationalism may as well scrap any hope of supplying adequate grounds for a noetic structure.

The Communities That Care (CTC) Family Attachment Scale: Measurement Invariance Across Family Structures

Familial protective factors are an integral part of prevention approaches aimed at problematic behaviour in adolescents. However, there is scarce evidence on the role of familial protective factors in families deviating from the two-parent family configuration. For evaluating targeted (preventive) interventions, a reliable and valid measurement of familial protective factors is crucial. We investigated the factor structure of the Communities That Care (CTC) Family Attachment Scale and tested its measurement invariance in different family structures. Adolescents (n?=?2.459, grades 6–11) from Lower Saxony, Germany filled in the German version of the CTC Youth Survey. Our analyses focused on the CTC Family Attachment Scale measuring the adolescent’s attachment to the mother and the father with six items. We evaluated the postulated unidimensional structure of the scale by confirmatory factor analysis (CFA) and tested the measurement invariance using multigroup factor analyses across different family structures (two-parent family/single-parent family). We used SPSS V.23 and the R packages lavaan and semTools. The two-factor solution for the CTC Family Attachment Scale with one factor representing attachment to the mother and one indicating attachment to the father had an adequate model fit in the total sample (χ²(5)?=?29.938; p?<?.001; CFI?=?.996; TLI?=?.988; RMSEA?=?.050, SRMR?=?.019). This two-factor solution of the CTC Family Attachment Scale showed strong measurement invariance regarding adolescents living in a two-parent family vs. those living with a single parent. The two-factor CTC Family Attachment Scale appears to be a suitable measure to assess family attachment in both two-parent and single-parent families with German adolescents.     

Benefits of expressive writing in lowering rumination and depressive symptoms

Depression-vulnerable college students (with both elevated prior depressive symptoms and low current depressive symptoms) wrote on 3 consecutive days in either an expressive writing or a control condition. As predicted, participants scoring above the median on the suppression scale of the Emotion Regulation Questionnaire (Gross & John, 2003) showed significantly lower depression symptoms at the 6-month assessment when they wrote in the expressive writing versus the control condition. Additional analyses revealed that treatment benefits were mediated by changes in the Brooding but not the Reflection scale of the Ruminative Response Scale (Nolen-Hoeksema & Morrow, 1991). A "booster" writing session predicted to enhance treatment benefits failed to have a significant effect.     

Children's Lived Spaces in the Inner City: Historical and Political Aspects of the Psychology of Place

Children's lives are tied to particular places, which are the stage where the psychological drama of the human community is played out. This biographical research study investigates and documents the experiences of children's lived spaces in Pittsburgh's Hill District. The Hill District is a traditionally immigrant and African American neighborhood, which has suffered through segregation, the turmoil of urban renewal, race riots, gang warfare, and drug-related crime. When we look at the history of a particular place, we often forget that its children are raised and participate in the same historical stream. What was childhood like for the children who grew up in The Hill over the past century?

Adapting the ethnographic method of narrative mapping (Lutz, Behnken, & Zinnecker, 1997 Lutz, M., Behnken, I. and Zinnecker, J. 1997. “Narrative Landkarten [Narrative maps]”. In Handbuch Qualitative Forschungmethoden in der Erziehungswissenschaft, Edited by: Friebertshäuser, B. and Prengel, A. 414–435. Germany: Juventa Verlag.. Weinheim und Muenchen [Google Scholar]), 12 African American adults (24 to 84 years old), who spent their childhoods in the Hill District, were interviewed and asked about their childhood roaming spaces. The story about lived space that emerged through the choral voices of the participants is of childhood places marked by political and cultural changes. Each generation of 10-year-olds (1930's to 2000) lived in the same geographical area, but experienced and lived their neighborhood places in dramatically different ways.
