Motivation for Dental Home Care: Testing a Self‐Determination Theory Model1

The present research developed the Self‐Regulation for Dental Home Care Questionnaire (SRDHCQ), based on self‐determination theory (SDT; Deci & Ryan, 2000 ), and used it in an SDT process model of dental health behaviors and self‐rated oral health. In this model, patients' perceptions of autonomy‐supportive (relative to controlling) dental professionals were expected to positively predict patients' psychological needs satisfaction in treatment. Needs satisfaction was expected to be positively related to autonomous motivation for dental home care and perceived dental competence, which were expected to be positively associated with self‐rated oral health and dental health behaviors. Confirmatory factor analysis of the 5‐factor SRDHCQ model fit the data very well, and a structural equation model supported the hypothesized process model.     

Word fluency performance and strategies in children with cochlear implants: age‐dependent effects?

Löfkvist, U., Almkvist, O., Lyxell, B. & Tallberg, I.‐M. (2012). Word fluency performance and strategies in children with cochlear implants: age‐dependent effects? Scandinavian Journal of Psychology 53, 467–474. Word fluency was examined in 73 Swedish children aged 6–9 years divided into two age groups, 6–7 and 8–9 years; 34 deaf children with cochlear implants (CI) (15 girls/19 boys) and 39 age‐matched children with normal hearing (NH) (20 girls/19 boys). One purpose was to compare the ability to retrieve words in two different word fluency tasks; one phonemically based (FAS letter fluency) and one semantically based (animal fluency). A second purpose was to examine retrieval strategies in the two tasks by conducting an analysis of clustering and switching of word sequences. In general we found that age was an important factor for word fluency ability, in both the CI and the NH groups. It was also demonstrated that children with CI aged 8–9 years retrieved significantly fewer words and used less efficient strategies in the retrieval process, especially on the phonemically based task compared to children with NH of the same ages, whereas children 6–7 years performed similarly in both groups regarding number of retrieved words and use of strategies. The results are discussed with respect to factors such as age differences in performance for children with CI, especially for the phonemically based task.     

Background beliefs and evidence interpretation

In this paper we argue that it is often adaptive to use one's background beliefs when interpreting information that, from a normative point of view, is incomplete. In both of the experiments reported here participants were presented with an item possessing two features and were asked to judge, in the light of some evidence concerning the features, to which of two categories it was more likely that the item belonged. It was found that when participants received evidence relevant to just one of these hypothesised categories (i.e. evidence that did not form a Bayesian likelihood ratio) they used their background beliefs to interpret this information. In Experiment 2, on the other hand, participants behaved in a broadly Bayesian manner when the evidence they received constituted a completed likelihood ratio. We discuss the circumstances under which participants, when making their judgements, consider the alternative hypothesis. We conclude with a discussion of the implications of our results for an understanding of hypothesis testing, belief revision, and categorisation.     

Play Behavior and Playfulness in Adulthood

Although research has established play behavior and playfulness as important to the well‐being of children and animals, researchers have not typically considered the importance or implications of play in human adults. This is surprising given that play behavior is a topic of high relevance to social psychology. Definitional issues, a lack of a theoretical framework, and a dearth of standardized measures have posed obstacles in the advancement of this interesting research area, which is ripe for investigation. In this review, we summarize the extant literature, identify strengths and weaknesses of this literature, propose definitions to guide future work in this area, identify relevant theories that may be expanded to provide a framework for programmatic research on play in adulthood, and elucidate avenues for future research. Our aim is to encourage the development of this research area within social psychology.     

Attachment Style,Assertive Communication,and Safer-Sex Behavior1

This research tested the proposition that the effect of attachment security on safer-sex practice may be mediated by communication patterns. One hundred eighty-five undergraduate students completed questionnaire measures of attachment, assertiveness, and attitudes to communication about AIDS. Eight weeks later, they reported on their practice of safer sex in the period since the first testing session. Hierarchical regressions showed that at Step I, anxiety about relationships (a measure of insecure attachment) was associated with less safer-sex practice, for all outcome measures. Attitudes to communication about AIDS added to the prediction of general reports of safer-sex practice: in line with the mediational model, anxiety about relationships became unimportant as a predictor when communication variables were included. Communication variables failed to add to the prediction of safer sex on the most recent encounter, and both anxiety about relationships and attitudes to communication about AIDS predicted condom use. Some gender differences in patterns of prediction were noted. The results are discussed in terms of attachment style and its links with the negotiation of sexual practice and relationship issues.     

Norepinephrine and brain damage: alpha noradrenergic pharmacology alters functional recovery after cortical trauma

The goal of these experiments was to evaluate the effects of some drugs affecting noradrenergic (NE) synaptic transmission, commonly prescribed following stroke or traumatic brain injury, on functional recovery. Measurement of recovery from a transient hemiplegia produced by a traumatic unilateral focal contusion in sensorimotor cortex (SMCX) of rats was used to assess the effects of chronic haloperidol (HAL) treatment begun early (1 day) or late (18 days to recovered animals) after injury. Additionally, using the same model, the effects of a single administration of drugs with selective action at NE receptors were also evaluated early or late (30 days) after injury. These drugs were: phenoxybenzamine (PBZ), an alpha 1-NE antagonist; prazosin (PRAZ), an alpha 1-NE antagonist; yohimbine (YOH), an alpha 2-NE antagonist; propranolol (PROP), a beta 1- and 2-NE receptor antagonist; methoxymine (METHOX), an alpha 1-NE agonist; and clonidine (CLON), an alpha 2-NE agonist. The data indicate that drugs with antagonistic effects at alpha 1 NE receptors, including HAL and PRAZ but not PROP, administered early after SMCX contusion retard locomotor recovery. Beneficial effects of enhancing NE transmission by METHOX or YOH were not observed. In animals recovered from beam walk (BW) deficits, a single administration of PBZ or PRAZ (alpha 1 NE antagonists) or CLON (alpha 2 NE agonist) transiently reinstated hemiplegic symptoms. The nonspecific beta NE receptor antagonist PROP had no effect in recovered animals. A single dose of HAL had no effect in recovered animals, but a BW deficit transiently developed in some animals following chronic treatment. The data are discussed with reference to drug contraindications noted in clinical studies of recovery from poststroke aphasia and cognition in demented patients with degenerative brain disease.     

An introductory statistics class and examination using SPSS/PC

SPSS/PC was integrated into lecture and an examination in introductory statistics. Students were given an anonymous questionnaire after a traditional examination and again after an examination with SPSS/PC. They wanted more theory and derivation and were ambivalent about SPSS/PC in lecture. The computer test decreased computational error fears. Students preferred the more realistic questions which the computer permitted. Test performance was not significantly different. The results suggest that statistical packages should be used in later courses rather than in introductory statistics.     

The Contingencies of Interpersonal Acceptance: When Romantic Relationships Function as a Self-Affirmational Resource

Existing research suggests that people with high, but not low, self-esteem use their dating partners' love and acceptance as a resource for self-affirmation when faced with personal shortcomings. The present research examines the role that perceived contingencies of acceptance play in mediating these effects. In Experiment 1, we activated either conditional or unconditional working models and then gave experimental participants failure feedback on an intelligence test. In Experiment 2, we activated thoughts of rejection (or control thoughts) and then gave experimental participants feedback suggesting that their romantic partners would discover their secret sides. Experiment 1 revealed that low and high self-esteem women both embellished their partners' love and acceptance to compensate for self-doubt when the unconditional audience was primed. When rejection was primed in Experiment 2, however, high self-esteem men reacted to the self-threat by doubting their partners' love. These findings suggest that people with low self-esteem may not typically use their relationships to self-affirm because contingencies linking failure to rejection and acceptance to success are chronically accessible in their interpersonal schemas.
