Social neuroeconomics: the neural circuitry of social preferences

Combining the methods of neuroscience and economics generates powerful tools for studying the brain processes behind human social interaction. We argue that hedonic interpretations of theories of social preferences provide a useful framework that generates interesting predictions and helps interpret brain activations involved in altruistic, fair and trusting behaviors. These behaviors are consistently associated with activation in reward-related brain areas, such as the striatum, and with prefrontal activity implicated in cognitive control, the processing of emotions, and integration of benefits and costs, consistent with resolution of a conflict between self-interest and other-regarding motives.     

Antecedents of Children's Adult Outcomes in the Texas Adoption Project

ABSTRACT Four composite variables concerning life outcomes were derived from a brief mail questionnaire describing 478 adults, now in their 30s and 40s, who had participated as children in the Texas Adoption Project. Responses were obtained from the participants themselves, their parents, and their siblings. MMPI scores of the parental generation were correlated with the adult outcomes of their biologically related and unrelated children. The obtained correlations were low, but for the biological relationships positive parent adjustment went with positive life outcomes of their children, whereas for adoptive relationships the reverse was the case. Favorable MMPI scores from late adolescence were favorably related to adult outcomes, as were favorable personality ratings from childhood.     

Predicate Logical Extensions of some Subintuitionistic Logics

The paper presents predicate logical extensions of some subintuitionistic logics. Subintuitionistic logics result if conditions of the accessibility relation in Kripke models for intuitionistic logic are dropped. The accessibility relation which interprets implication in models for the propositional base subintuitionistic logic considered here is neither persistent on atoms, nor reflexive, nor transitive. Strongly complete predicate logical extensions are modeled with a second accessibility relation, which is a partial order, for the interpretation of the universal quantifier.

‘Can you push a camel through the eye of a needle?’ Reflections on how the unconscious speaks to us and its clinical implications

There has been a recent surge of interest in a type of thinking seen in some patients most of the time, and all patients some of the time. In the past it was simply called regressive thinking, but attempts to be more specific have led it to be called by various names, like 'pre-symbolic', 'pre-conceptual' and 'pre-operational'. What these labels attempt to capture is that the patient's thinking, at these times, is without representations and closer to actions. As a clinical phenomena I prefer to use Loewald's term, 'action–language', that is, where words become attempts to bore, seduce, anger, etc. It is different from when words are used to communicate internal states via free association. A case is made for action–language being the primary method by which the unconscious speaks to us in psychoanalytic treatment. This paper explores some of the reasons for this type of thinking, along with the clinical methods to find the thinker where there appears to be none. Distinctions will be made as to the use of the process versus the content, on the goal of interventions as bringing insight versus the capacity for insightfulness, and the model of treatment as leading to transformations in thinking, rather than lifting of repressions. A clinical example is presented to demonstrate these perspectives.     

Mediating and Moderating Processes in the Relation between Maltreatment and Psychopathology: Mother-Child Relationship Quality and Emotion Regulation

The present study investigated underlying processes of the effect of maltreatment on psychopathology (i.e., internalizing and externalizing problems) in a group of 111 maltreated and 110 nonmaltreated 7–10 year-old children (60% boys). We tested the moderating and/or mediating roles of emotion regulation and the mother-child relationship quality (pattern of relatedness) using Structural Equation Modeling. Emotion regulation, but not the pattern of relatedness, mediated the relation between maltreatment and psychopathology. This mediation was moderated by the pattern of relatedness: For the group of children with an insecure pattern of relatedness, maltreatment was related to lower levels of emotion regulation, which was predictive of higher levels of internalizing and externalizing symptomatology. In contrast, for the secure relatedness group, there was no mediation by emotion regulation since the impact of maltreatment on emotion regulation was not significant. Implications of the mediating role of emotion regulation and the buffering role of the mother-child relationship quality were discussed.

An empirical analysis of driver perceptions of the relationship between speed limits and safety

In recent decades, it has become more common for speed limits to be set for political reasons rather than for safety reasons. As a consequence, the motoring public seems to have increasingly begun questioning the rationality of speed limits. This is evident in observed speed data that show that the majority of drivers routinely exceed posted speed limits. A key motivating factor in drivers’ tendency to exceed the speed limit is that they believe that the excess speed does not threaten safety. This paper, specifically studies this matter by using a survey that asked drivers how fast above the speed limit they feel they can drive before safety is threatened. A probabilistic model is estimated using data gathered from 988 drivers in Indiana. Estimation findings show that drivers’ perception of the speed above the speed limit at which they will receive a speeding ticket is a critical determinant of what they believe is a safe speed – suggesting that enforcement plays an important role in safety perceptions. Other variables found to be significant factors in determining the speed above the speed limit at which safety is first threatened include age, gender, being previously stopped for speeding, and drivers’ ethnicity.     

What's in a name? Attachment-related attentional bias

Participants completed a dot probe task that presented pairs of first names: the participant's own name and a neutral name (Experiments 1-4), the name of their attachment figure and a neutral name (Experiments 1-4), or the name of a known person and a neutral name (Experiments 2-4). A significant attentional bias effect was found for the attachment name in attachment-related contexts, whether they were threatening or positive. The results of Experiments 2 and 4 showed that the attentional bias effects for the attachment name were not driven by familiarity effects and could not be interpreted in terms of salience. Attachment anxiety was associated with hypervigilance toward the attachment name in threatening and positive attachment contexts. Attachment avoidance was unrelated to any attentional bias effects.     

Attention for emotional faces under restricted awareness revisited: do emotional faces automatically attract attention?

Theoretical models of attention for affective information have assigned a special status to the cognitive processing of emotional facial expressions. One specific claim in this regard is that emotional faces automatically attract visual attention. In three experiments, the authors investigated attentional cueing by angry, happy, and neutral facial expressions that were presented under conditions of limited awareness. In these experiments, facial expressions were presented in a masked (14 ms or 34 ms, masked by a neutral face) and unmasked fashion (34 ms or 100 ms). Compared with trials containing neutral cues, delayed responding was found on trials with emotional cues in the unmasked, 100-ms condition, suggesting stronger allocation of cognitive resources to emotional faces. However, in both masked and unmasked conditions, the hypothesized cueing of visual attention to the location of emotional facial expression was not found. In contrary, attentional cueing by emotional faces was less strong compared with neutral faces in the unmasked, 100-ms condition. These data suggest that briefly presented emotional faces influence cognitive processing but do not automatically capture visual attention.     

A time-course analysis of attentional cueing by threatening scenes

Models of attention and emotion have assigned a special status to the processing of threatening information: Facilitated attentional capture by threat and its prioritized processing would allow for swift and adequate action to potentially dangerous stimuli. In four experiments, we examined the time-course of facilitated orienting of attention to threatening scenes in the exogenous cueing paradigm. Threat value and presentation duration of the cues were systematically varied. Facilitated attentional capture by threat was limited to highly threatening pictures presented for 100 ms. No attentional effects were observed with a 28 ms cue presentation duration. At slightly longer cue presentations, 200 ms and 500 ms, results indicated no and even reduced attentional capture by threat compared with neutral information. The present results provide support for the idea that threat facilitates fast attentional orienting to its location, followed by the inhibition of attention to threat.
