Lay theories of self‐control influence judgments of individuals who have failed at self‐control

Individuals who have failed at self‐control are often the targets of negative social judgments. We suggest that in some circumstances, individual differences in lay theories regarding self‐control may help account for these reactions. Specifically, people may believe that the ability to exert self‐control is either a fixed quantity (entity theory) or a malleable quantity (incremental theory), and these beliefs may influence their social judgments. In the current investigation, we found that whether lay theories of self‐control were measured or manipulated, entity views of self‐control predicted more negative judgments about a target whose self‐control failure was made salient.

Influences of culture and visual context on real-time social categorization

Social categorization is often thought to be based on facial features and immune to visual context. Moreover, East Asians have been argued to attend to context more than Westerners. American and Chinese participants were presented with faces varying along a White-Asian morph continuum either in American, neutral, or Chinese contexts. American contexts made White categorizations more likely, and Chinese contexts made Asian categorizations more likely. Further, the compatibility between facial and contextual cues influenced the directness of participants' hand trajectories en route to selecting a category response. Even when an ultimate response was not biased by context, the trajectory was nevertheless partially attracted to the category response associated with the context. Importantly, such partial attraction effects in hand trajectories revealed that the influence of context began earlier in time for Chinese relative to American participants. Together, the results show that context systematically influences social categorization, sometimes altering categorization responses and other times only temporarily altering the process. Further, the timing of contextual influences differs by culture. The findings highlight the role of contextual and cultural factors in social categorization.     

论证有几种类型？

对于论证中理由的充分性,可以从两个维度来加以分析,一个是从逻辑上,一个是从认识论上。基于此,本文提出了一种新的论证类型理论。从逻辑上而言,论证中从前提推至结论的过程,它可能是确凿无疑的,也可能仅仅是可废止的。从认识论上来看,能够保证论证成立的依据,其正当性可能被先验地证成,也可能是被后验地证成。因此,论证可以区分为如下四种类型：先验并确凿无疑、先验且可废止、后验且可废止、以及表面上看似的后验并确凿无疑。此外,也有一些论证,其成立依据可能同时涉及到先验和后验的证成。本文给出了以上各种论证类型的具体例示,并将这一新的分类方法与其它论证类型理论进行了比较。     

Perceptions of health care social workers in Ontario: challenges and facilitators to reflective practice

Background: Reflective practice in health care social work ensures that social workers provide effective and efficient services to clients as well as maintaining their mental and physical health. In this study, we aim to determine how health care social workers engage in and describe reflective practice and challenges related to their reflective practice in their work in the health care system.

Methods: We used the Reflective Dialogue Rating Scale (RDRS) developed by Marion Bogo et al. to structure qualitative face-to-face interviews with 23 health care social workers employed in a hospital in a large urban area in Ontario, Canada.

Results: Findings illustrated that all participants regularly engaged in reflective practice in order to carry out everyday social work activities, promote ethical practice, and to enhance the provision of services to their clients. The social worker participants consistently agreed that as a profession they faced challenges maintaining their knowledge of current research due to few opportunities for professional development, workload competing with educational opportunities, and a work climate that is not conducive to gaining professional development, thereby challenging reflective practice. Supportive working environments include: peer supervision, safe and private spaces to talk to colleagues, a supportive supervisor, and an overall positive organizational culture.

Discussion and conclusion: Reflective practice is a key component in health care social work. All 23 social workers stated that they used reflective techniques (such as peer supervision and debriefing) to deal with their own reactions and operated in a purposeful and intentional manner to form therapeutic relationships with clients. As such, participants stated that lifelong learning was paramount in providing quality care to clients.     

Perception as interacting psychophysical functions. Could the configuring of features replace a specialised receptor?

This paper illustrates how perception is achieved through interactions among the psychophysical functions of judged features of an object. The theory is that the perceiver places processed features in a multidimensional space of discriminal processes. Each dimension is scaled in units of discrimination performance. The zero coordinate of each feature is its level in an internal standard (norm) established by previous experience of that category of object in context. Experiments are reported which show that one, two, or three concurrent single-featured objects matched the multiple features of another object in two ways. Either stimulation from the two objects had discrimination distances from norm that added, or the stimulation by one object was processed through a concept describing stimulation by the other object. It follows that, in this case, perception via a receptor for the multi-featured object can be replaced by a point of balance among receptors for each single feature. The object with its own receptor is the gustatory stimulant L-glutamic acid as its monosodium salt. The features that stimulate diverse gustatory receptors of their own are sodium chloride, citric acid, sucrose, and caffeine. A more complex approach to dimensional coding was developed earlier for photoreceptors in colour judgments. The present approach is modality independent, mathematically simple, and economical in experimental data.     

Healing Men and Community: Predictors of Outcome in a Men’s Initiatory and Support Organization

Men have poorer health and declining social outcomes when compared to women, and research suggests that behaviors related to restrictive and traditional male gender roles contribute to this disparity. This study is an examination of The ManKind Project International (MKPI), a community-based organization that provides alternative male gender norms and a community support system to help reinforce them. The MKPI runs an intensive, experiential “Training Adventure Weekend” (TAW), followed by voluntary, on-going peer-led support and integration groups (I-Groups). One hundred men completed a pre-TAW questionnaire, an interview, and a long-term follow-up (>18 mo.) questionnaire. The study examined if there was change on the primary study variables at follow-up, and the relationship of background characteristics (age, self-help group experience) and factors related to participation (MKPI beliefs, social support, I-Group participation) to the criterion variables (depression symptoms, gender role conflict, and life satisfaction) at follow-up. Results indicated significant change in the expected directions on the primary study variables, suggesting that for these men, participation has a positive impact. Most importantly, changes in MKPI-related beliefs and social support significantly predicted positive outcomes. Also, more positive outcomes were found among men 30–44 years of age, but not among those with more prior self-help experience or I-Group participation. Possible explanations for these findings and directions for further research are discussed.     

Medial auditory thalamic input to the lateral pontine nuclei is necessary for auditory eyeblink conditioning

Auditory and visual conditioned stimulus (CS) pathways for eyeblink conditioning were investigated with reversible inactivation of the medial (MPN) or lateral (LPN) pontine nuclei. In Experiment 1, Long-Evans rats were given three phases of eyeblink conditioning. Phase 1 consisted of three training sessions with electrical stimulation of the medial auditory thalamic nuclei (MATN) paired with a periorbital shock unconditioned stimulus (US). An additional session was given with a muscimol (0.5 μL, 10 mM) or saline infusion targeting the LPN followed by a recovery session with no infusions. The same training and testing sequence was then repeated with either a tone or light CS in phases 2 and 3 (counterbalanced). Experiment 2 consisted of the same training as Experiment 1 except that muscimol or saline was infused in the MPN during the retention tests. Muscimol infusions targeting the LPN severely impaired retention of eyeblink conditioned responses (CRs) to the MATN stimulation and tone CSs but only partially reduced CR percentage to the light CS. Muscimol infusions that targeted the MPN had a larger effect on CR retention to the light CS relative to MATN stimulation or tone CSs. The results provide evidence that the auditory CS pathway necessary for delay eyeblink conditioning includes the MATN-LPN projection and the visual CS pathway includes the MPN.
