The control of movement in the preferred and non-preferred hands

The nature of the difference in skill between the preferred and non-preferred hands was investigated using a peg-board task. The first experiment examined the effects of varying movement amplitude and target tolerance on performance. The difference between hands was found to be related to tolerance rather than movement amplitude. The second study analysed a film record of well-practised subjects, confirming the hypothesis that most of the difference between hands is due to relative slowness of the non-preferred hand in the positioning phase involving small corrective movements. Analysis of the type and number of errors further suggested that this result is not due to differences in duration of movements but to their increased frequency, implying greater accuracy of aiming with the preferred hand. Thus whilst the initial gross analysis implicated feedback processing in skill differences the more detailed analysis suggests that motor output of the nonpreferred hand is simply more variable.     

The social psychological power of photography: can the image‐freezing machine make something of nothing?

Sontag ( 1990 ) proposed that taking a photograph imparts social significance to the moment being captured. Two experiments were conducted to examine how the experience of being photographed affects the social relations of those who are photographed. In Experiment 1 (N=92), unacquainted members of dyads who were photographed together and then saw the resulting image displayed greater social self‐categorization and greater affinity for each other than did dyads who were not photographed (p<0.05). In Experiment 2 (N=282), pairs of photographed strangers also displayed greater social self‐categorization and mutual affinity than pairs of nonphotographed strangers (p<0.05). This effect occurred whether pair members were explicitly framed together in photographs or not. This result was unaffected by whether the photographed strangers were shown or were not shown their photograph. Merely opening and closing the shutter of a camera was sufficient for the development of a photo‐bonding effect. Results are discussed in terms of how the experience of being photographed can affect interpersonal perception and relationship formation. The significance of being photographed (Milgram, 1977 ; Sontag, 1990 ) apparently is so strong that it promotes social self‐categorization (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987 ) both when people are photographed simultaneously and sequentially.

Multimodal access to verbal name codes

Congruent information conveyed over different sensory modalities often facilitates a variety of cognitive processes, including speech perception (Sumby & Pollack, 1954). Since auditory processing is substantially faster than visual processing, auditory-visual integration can occur over a surprisingly wide temporal window (Stein, 1998). We investigated the processing architecture mediating the integration of acoustic digit names with corresponding symbolic visual forms. The digits "1" or "2" were presented in auditory, visual, or bimodal format at several stimulus onset asynchronies (SOAs; 0, 75, 150, and 225 msec). The reaction times (RTs) for echoing unimodal auditory stimuli were approximately 100 msec faster than the RTs for naming their visual forms. Correspondingly, bimodal facilitation violated race model predictions, but only at SOA values greater than 75 msec. These results indicate that the acoustic and visual information are pooled prior to verbal response programming. However, full expression of this bimodal summation is dependent on the central coincidence of the visual and auditory inputs. These results are considered in the context of studies demonstrating multimodal activation of regions involved in speech production.     

Fishing For Feelings? Hooking Viewers Helps!

To better understand individual variation in emotional responses to advertising, the authors recommend considering 3 general factors: characteristics of the individual who sees the ad, characteristics of the ad itself, and the nature of the ad–individual interface. This article examines 1 aspect of the individual, affect intensity (AI); one aspect of the ad, the degree to which the ad tells a story; and 1 aspect of the ad–individual interface, whether the individual is hooked by the ad. Experimental results reveal that an individual's being hooked by an ad has a positive relation with upbeat and warm feelings, a negative relation with disinterested feelings, and significantly enhances the viewer's attitude toward the ad. We find that AI has a positive relation with upbeat and warm feelings, and AI moderates the effect of being hooked on upbeat and warm feelings. Findings also reveal that narrative ad structure has a positive relation with upbeat and warm feelings, a negative relation with disinterested feelings, and that being hooked moderates the effect of narrative ad structure on upbeat and warm feelings responses.     

Cross-linguistic phonotactic competition and cognitive control in bilinguals

The current study examines the relation between cognitive control and linguistic competition resolution at the sublexical level in bilinguals. Twenty-one Spanish–English bilinguals and 23 English monolinguals completed a non-linguistic Stroop task (indexing inhibitory control) and a linguistic priming/lexical decision task (indexing Spanish phonotactic-constraint competition during English comprehension). More efficient Stroop performance (i.e. a smaller Stroop effect) in bilinguals was associated with decreased competition from Spanish phonotactic constraints during English comprehension. This relation was observed when nonword targets overlapped in phonotactic constraints and phonological form with preceding cognate primes (e.g. prime: stable (Spanish: estable)/target: esteriors). Findings suggest a link between non-linguistic cognitive control and co-activation of linguistic structures at the sublexical level in bilinguals.     

“Hey,let me hold your guns for a while”: A qualitative study of messaging for firearm suicide prevention

A recommended component of suicide prevention is encouraging at‐risk individuals to voluntarily and temporarily reduce access to firearms and other lethal methods. Yet delivering counseling on the topic can be difficult, given the political sensitivity of firearm discussions. To support such counseling, we sought to identify recommended framing and content of messages about reducing firearm access for suicide prevention. Through qualitative interviews with firearm owners and enthusiasts, we identified key points for use in framing (identity as a gun owner, trust, voluntary and temporary storage, and context and motivation) and specific content (preference for “firearm” over “gun,” and legal issues such as background checks for transfers). These findings build on prior work and should enhance efforts to develop and deliver effective, acceptable counseling and—ultimately—prevent firearm suicide.     

Attachment Representation and Sensitivity: The Moderating Role of Posttraumatic Stress Disorder in a Refugee Sample

It has been hypothesized that adult attachment representations guide caregiving behavior and influence parental sensitivity, and thus affect the child's socio‐emotional development. Several studies have shown a link between posttraumatic stress disorder (PTSD) and reduced parental sensitivity, so it is possible that PTSD moderates the relationship between insecure attachment representations and insensitivity. In this study symptoms of PTSD (Harvard Trauma Questionnaire), parental sensitivity (Emotional Availability Scales), and attachment representations (Attachment Script Assessment) were assessed in 53 parents who were asylum seekers or refugees. Results showed that when parents were less able to draw on secure attachment representations, symptoms of PTSD increased the risk of insensitive parenting. These findings suggest that parental sensitivity is affected not just by attachment representations, but by a conjunction of risk factors including symptoms of PTSD and insecure attachment representations. These parents should therefore be supported to establish or confirm secure models of attachment experiences, to facilitate their ability interact sensitively and form a secure relationship with their children.
