The “Longing for Interpersonal Touch Picture Questionnaire”: Development of a new measurement for touch perception

Touch is a crucial factor of physiological and psychological health in humans. A lack of touch in contrast is associated with adverse implications on mental health. A new “Longing for Interpersonal Touch Picture Questionnaire (LITPQ)” was developed and tested for its concurrent, predictive, discriminant and face validity as well as its relation to psychological distress. Six different types of touch were depicted and touch frequency and touch wish concerning different interaction partners assessed. A sample of 110 participants aged 18–56 years completed the LITPQ as well as an existing touch deprivation questionnaire and a questionnaire on mental health. Frequency and wish for touch were higher for close interaction partners than for strangers. For 72.7% of the participants, their touch wish exceeded the reported touch frequency. The LITPQ correlated moderately with the existing questionnaire for touch deprivation and was independent of relationship status or gender but positively correlated with depressiveness, anxiety and somatization. Measuring longing for touch is a very complex task considering the many aspects of subjective touch perception and confounds in the method of self-report of touch. In our view, the LITPQ provides promising insights into this matter.     

A cross-linguistic data bank for oral picture naming in Dutch, English, German, French, Italian, Russian, Spanish, and Swedish (PEDOI)

The well established effect of word frequency on adult's picture naming performance is now called into question. This is particularly true for variables which are correlated with frequency, as is the case of age of word acquisition. Since the work of [Carrol and White, 1973] there is growing agreement among researchers to confer an important role in lexical access to this variable. Indeed, it has been shown ( [Hodgson and Ellis, 1998]) that for normal English-speaking adults only the variables 'age-of-acquisition' and 'name agreement' are independent predictors of naming success among the various variables considered. However, when brain-damaged subjects with and without degenerative pathologies are studied, word frequency and word length as well as concept familiarity all give significant effects ( [Hirsh and Funnell, 1995]; [Lambon Ralph et al., 1998]; [Nickels and Howard, 1995]). Finally, it has been suggested that the production of specific error types may be related to such variables. According to [Nickels and Howard, 1994] the production of semantic errors is specifically affected by 'imageability' and in the recent study by [Kremin et al., 2001] 'age of acquisition' predicts (frank) word finding difficulties.     

Unambiguous generalization effects after treatment of non-canonical sentence production in German agrammatism

Agrammatism is-among others, characterized by a deficit in producing grammatical structures. Of specific difficulty is the utilization of complex, non-canonical sentence structures (e.g. object-questions, passives, object-clefts). Several studies have documented positive effects when applying a specific treatment protocol in terms of increasingly correct production of target complex sentence structures with some variance in generalization patterns noted across individuals. The objective of this intervention study was to evaluate an intervention program focussing on the production of non-canonical sentences. Hypotheses about the occurrence of treatment effects were formulated on the basis of syntactic complexity, referring to the amount of syntactic phrase structures necessary to generate specific German sentence structures. A multiple single case study with seven agrammatic participants was applied, each participant receiving training in the production of object-relative-clauses and who-questions. The investigation was designed to unambiguously evaluate for each individual, structure specific and generalized learning effects with respect to the production of object-relative-clauses, who-questions and passive sentences. Results showed significant improvements for all sentences types. This outcome is considered within methodological issues of treatment studies. Theoretical and clinical implications are discussed.     

Paranormal Believers' Susceptibility to Confirmatory Versus Disconfirmatory Conjunctions

This study examines paranormal believers' susceptibility to the conjunction fallacy for confirmatory versus non‐confirmatory conjunctive events. Members of the UK public (N = 207) read 16 hypothetical vignettes before judging the likelihood that each constituent and their conjunction would (co) occur. Event type (paranormal versus non‐paranormal), outcome type (confirming versus disconfirming) and level of paranormal belief (in either extrasensory perception, psychokinesis or life after death)—plus relevant interaction terms—were entered into a linear mixed model analysis. As hypothesised, paranormal belief was associated with more conjunction errors regardless of event type with, in general, more errors made for confirmatory over disconfirmatory conjunctions. These trends existed for extrasensory perception and psychokinesis believers with those for life after death believers approaching significance. Consistent with Crupi and Tentori's Confirmation–Theoretical Framework, current findings suggest that paranormal believers are prone to a generic and confirmatory conjunction fallacy. Theoretical implications, methodological limitations and future research ideas are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Efficacy of Parent-Child Interaction Therapy with Parents with Intellectual Disability

Parents with intellectual disability (ID) face many parenting challenges that may affect their ability to parent effectively, and such deficits are often associated with various poor child outcomes. Research findings are inconsistent for interventions targeting systematic skills for parents with ID. Parent-Child Interaction Therapy (PCIT) is an empirically supported treatment that incorporates performance-based training to enhance parenting ability. This study evaluated implementation of PCIT with parents with ID using a multiple baseline design across behaviors. Results suggest increases in positive parenting behaviors and consistent discipline. However, limitations related to poor maintenance and generalization warrant the need for future research.     

Cooling blocks ITM and LTM formation and preserves memory

In Lymnaea aerial respiratory behaviour can be operantly conditioned; snails learn not to perform this behaviour. Depending on the training procedure used, snails are competent to form either intermediate-term (ITM; lasting 1-3 h) or long-term (LTM; >4 h) memory. We found that cooling the snails for 1 h immediately after training was sufficient to block either ITM or LTM. Cooling snails for a similar period 10 or 15 min after cessation of training, failed to block ITM and LTM formation, respectively. Finally, we employed the cooling technique to extend both ITM and LTM. That is, cooling could prevent forgetting. Cooling extended LTM that normally persisted for 2 days to at least 8 days. These data are consistent with the hypothesis that forgetting is due to the learning and remembering of interfering events, and thus is an active process.
