Effects of Trait Self‐Control on Response Conflict About Healthy and Unhealthy Food

Self‐control leads to positive life outcomes, but it is poorly understood. While previous research has focused on self‐control failure, self‐control success remains unexplored. The current studies aim to shed more light on the mechanisms of self‐control by focusing on the resolution of response conflict as a key component in self‐control success. Trait self‐control was measured, and participants reported on the magnitude of response conflict they experienced about healthy and unhealthy foods in Study 1 (N = 146; M_age = 33.03; 59 females, 83 males, 4 unknown). The response conflict process was assessed in Study 2 (N = 118; M_age = 21.45; 68 females, 41 males, 9 unknown). Outcomes showed that self‐reported evaluative response conflict about food items was smaller for people high in trait self‐control. Study 2 revealed that higher trait self‐control predicted faster resolution of self‐control conflict, and an earlier peak of the response conflict. Taken together, these results provide insight into what makes people with high trait self‐control successful, namely, how they handle response conflict. Implications for self‐control theories and future directions are discussed.     

How Job Insecurity Affects Political Attitudes: Identity Threat Plays a Role

This study tests the assumption that job insecurity threatens people’s work-related identities and thereby affects their political attitudes. Work-related identity threat in times of job insecurity is proposed to happen in two ways: people will fear to lose an important part of their identity (their identity as employed people), and they can also be afraid to gain a negative identity (their feared future self of becoming unemployed). Both identity threats are proposed to lead to more antiegalitarian attitudes and more political leaning to the right. A four-wave study among 969 employed British employees delivers support for some of the assumptions. In line with the expectations, results of time-stable structural equation modeling show that job insecurity indeed threatens the identity as an employed person, which leads to an increase in antiegalitarian attitudes over time. Different than expected, identity threat in the form of a heightened identification with the unemployed was not found. Also, people who identified more as unemployed people actually reported fewer antiegalitarian attitudes and shifted their political standing more to the left.     

The influence of decision task and deliberation style on the verdict of the juries

The influence of decision task and deliberation style on the verdict of the juries. In the Kameda's Deliberation Style Model the emission of verdicts of responsibility when the deliberation style of the juries (elemental/compound) and the type of decision task (disjunctive/conjunctive) are jointly manipulated, is favoured in certain conditions. Given the consequences that these approaches could have in real judicial processes, this model is analyzed using a manslaughter crime under the Spanish judicial context conditions (nine members juries and seven or five members majorities emitting a verdict of guilty or not guilty, respectively). The obtained results indicated a better operation of the model when a conjunctive decision task was demanded.     

Are people with high and low mental rotation abilities differently susceptible to the alignment effect?

We investigated whether the alignment effect (Levine et al, 1982 Journal of Experimental Psychology: General 111 157-175) is influenced by mental rotation abilities. In two experiments, groups of undergraduate students with high and low performance in mental rotation tasks were required to study either schematic (experiment 1) or more complex (experiment 2) maps, and to perform a number of pointing tasks adopting a perspective which could be aligned, misaligned (45 degrees, 135 degrees), or counteraligned (180 degrees) with the perspective assumed during learning. Cognitive styles in spatial representation have also been considered. Results of experiment 1 show that people with low performance in mental rotation tasks prefer to adopt a representation of space focused more on landmarks. Their performance in the pointing tasks depends on the alignment conditions, with more errors in the counteraligned condition followed by the two misaligned and aligned ones. In contrast to this, high-ability mental rotators prefer survey and route spatial representations and are affected only by the aligned and non-aligned conditions. In the second experiment, practice was studied as a function of mental rotation and alignment. The group high in mental rotation ability was found to be free from the alignment effect in the pointing tasks performed after the final of four learning phases.     

Wistar rats show episodic-like memory for unique experiences

Human episodic memory refers to the recollection of an unique past experience in terms of its details, its locale, and temporal occurrence. Episodic memory, even in principle, has been difficult to demonstrate in non-verbal mammals. Previously, we provided evidence that mice are able to form an integrated memory for "what," "where," and "when" aspects of single experiences by combining different versions of the novelty-preference paradigm, i.e., object recognition memory, the memory for locations in which objects were explored, and the temporal order memory for objects presented at distinct time points. In the present series of experiments we evaluated whether this paradigm, with minor modifications, also works with rats. We found that rats spent more time exploring an "old familiar" object relative to a "recent familiar" object, suggesting that they recognized objects previously explored during separate trials and remembered their order of presentation. Concurrently, the rats responded differentially to spatial object displacement dependent on whether an "old familiar" or "recent familiar" object was shifted to a location, where it was not encountered previously. These results provide strong evidence that the rats established an integrated memory for "what," "where," and "when." We also found that acute stress impaired the animal's performance in the episodic-like memory task, which, however, could be partially reversed by the N-Methyl-D-aspartate-receptors agonist D-cycloserine.     

Impairment of syntax and lexical semantics in a patient with bilateral paramedian thalamic infarction

Bilateral vascular thalamic lesions are rare. Although a variety of neurobehavioral manifestations have been described, the literature is less documented with regard to accompanying linguistic disturbances. This article presents an in-depth neurolinguistic analysis of the language symptoms of a patient who incurred bilateral paramedian ischemic damage of the thalamus. In the post-acute phase of the stroke, a unique combination of transcortical sensory aphasia with syntactic impairment was found. Because of this atypical semiological association, additional analyses of spontaneous speech were performed. In spite of the typological affinity with the grammatic characteristic of marked simplification of syntax observed in Broca's aphasia, only a wordclass specific, lexical-semantic deficit for verbs was objectified. The hypothesis that lexical-semantic disturbances in our patient might result from a functional deafferentiation of both thalami with the frontal lobe is supported by: (1) associated neuropsychological deficits of frontal origin and (2) frontal-like behavioral disturbances.     

Phonological encoding in the silent speech of persons who stutter

The purpose of the present study was to investigate the role of phonological encoding in the silent speech of persons who stutter (PWS) and persons who do not stutter (PNS). Participants were 10 PWS (M=30.4 years, S.D.=7.8), matched in age, gender, and handedness with 11 PNS (M=30.1 years, S.D.=7.8). Each participant performed five tasks: a familiarization task, an overt picture naming task, a task of self-monitoring target phonemes during concurrent silent picture naming, a task of monitoring target pure tones in aurally presented tonal sequences, and a simple motor task requiring finger button clicks in response to an auditory tone. Results indicated that PWS were significantly slower in phoneme monitoring compared to PNS. No significant between-group differences were present for response speed during the auditory monitoring, picture naming or simple motor tasks, nor did the two groups differ for percent errors in any of the experimental tasks. The findings were interpreted to suggest a specific deficiency at the level of phonological monitoring, rather than a general monitoring, reaction time or auditory monitoring deficit in PWS. Educational objectives: As a result of this activity, the participant should: (1) identify and assess the literature on phonological encoding skills in PWS, (2) enumerate and evaluate some major psycholinguistic theories of stuttering, and (3) describe the mechanism by which defective phonological encoding can disrupt fluent speech production.     

Does neuroscience hold promise for the further development of behavior therapy? The case of emotional change after exposure in anxiety and depression

Over the last few years, the integration of biological and psychological models has become increasingly important in clinical psychology. This paper presents a neurobiological framework for exploring how neuroscience research may be valuable in the context of new developments in behavior therapy. The importance of the cortical-subcortical circuitry of emotion processing for investigating the working mechanisms of exposure therapy is illustrated by current neuroimaging research. The implication is that during exposure therapy the focus of attention must be fully directed towards the emotional content of the threatening situation to facilitate prefrontal control over the amygdala and that new contextual information, of emotional salience, must be added to create inhibitory projections from the hippocampus. In addition, some possible mechanisms of action for different therapeutic approaches to both anxiety and depression and the role of neuroimaging techniques in predicting treatment outcome are discussed.
