The Motivational Impact of Perceived Control on Behavioral Intentions

This research explores the moderated influence of perceived control and its underlying motivational processes. Perceptions of control can change one's motivation to engage in deliberative or nondeliberative processing when forming a behavioral intention. Studies were designed to test the moderated relationships of perceived control on decision theoretic variables (Study 1), to provide experimental evidence of differences in processing relative to levels of perceived control (Study 2), and to examine how levels of control induce motivation to engage cognitive resources toward a decision (Study 3). Findings support predictions that lower vs. higher levels of control result in the formation of behavioral intention based on deliberative rather than nondeliberative processing. Theoretical implications of the findings are discussed.     

Differential patterns of spontaneous experiential response to a hypnotic induction: A latent profile analysis

A hypnotic induction produces different patterns of spontaneous experiences across individuals. The magnitude and characteristics of these responses covary moderately with hypnotic suggestibility, but also differ within levels of hypnotic suggestibility. This study sought to identify discrete phenomenological profiles in response to a hypnotic induction and assess whether experiential variability among highly suggestible individuals matches the phenomenological profiles predicted by dissociative typological models of high hypnotic suggestibility. Phenomenological state scores indexed in reference to a resting epoch during hypnosis were submitted to a latent profile analysis. The profiles in the derived four-class solution differed in multiple experiential dimensions and hypnotic suggestibility. Highly suggestible individuals were distributed across two classes that exhibited response patterns suggesting an inward attention subtype and a dissociative subtype. These results provide support for dissociative typological models of high hypnotic suggestibility and indicate that highly suggestible individuals do not display a uniform response to a hypnotic induction.     

Trust and distrust: the perception of trustworthiness of faces in psychopathic and non-psychopathic offenders

Psychopathy is a disorder linked to impairments in social cognition. Individuals with psychopathy and comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), completed a task requiring complex social judgments. Participants viewed a series of male faces, and made judgments concerning how trustworthy they considered the person pictured to be and the degree to which each face was displaying specific emotions. Judgments of trustworthiness did not differ between the individuals with psychopathy and the comparison individuals. Trustworthiness judgments of the faces negatively correlated with, in particular, ratings of anger in the faces for both groups of participants. The data are discussed with reference to the neural systems, including the amygdala, considered to be involved in the mediation of task performance and also neuro-cognitive models of psychopathy.     

The use of Afrocentric features as cues for judgment in the presence of diagnostic information

Prior research has shown that within racial category, group members with more Afrocentric facial features are presumed to have more stereotypic traits than those with less Afrocentric features. The present experiment investigated whether this form of feature‐based stereotyping occurs when more diagnostic information is available. The participants were provided with photographs and information about the aggressive (or non‐aggressive) behaviour of 64 African Americans in four different situations, and asked to predict the likelihood of aggression in a fifth situation. As expected, each instance of aggression increased estimates that a target would behave aggressively in the unknown situation. With degree of displayed aggression controlled, however, targets with more Afrocentric features were judged as significantly more likely to behave aggressively than targets with less Afrocentric features. Thus, stereotyping based on Afrocentric features occurs even when other obviously‐relevant information is available. This suggests that it may be difficult to detect and avoid.

The relation between employee organizational and professional development activities

A model is presented showing hypothesized common and parallel antecedents of employee organizational development activity (ODA) versus professional development activity (PDA). A common antecedent is expected to affect both ODA and PDA, while a parallel antecedent is expected to affect its corresponding work referent. This model was tested using a sample of 197 medical technologists over a four year time period. Prior ODA and PDA were controlled for before testing hypotheses. Results showed that the common antecedent of learning motivation was a robust indicator of both ODA and PDA. Looking at parallel antecedents, job satisfaction and affective organizational commitment had a positive impact on ODA, while occupational satisfaction and affective occupational commitment had a positive impact on PDA. ODA had a negative impact on subsequent intent to leave organization, but PDA did not have a similar impact on intent to leave profession. Study limitations, issues around operationalizing ODA and PDA, and future research directions are discussed.     

Maternal and child contributions to cortisol response to emotional arousal in young children from low-income, rural communities

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families from predominantly low-income, rural communities. Maternal behavior, family income-to-need ratio and social advantage, and child temperament, attention, and mental development were assessed, and children's saliva was sampled before and after standardized procedures designed to elicit emotional arousal. Maternal engagement in infancy was associated with greater cortisol reactivity at the infancy assessment and with reduced overall cortisol level at the toddler assessment. Also at the toddler assessment, child attention, mental development, and temperamental distress to novelty were associated with increased cortisol reactivity and regulation, whereas temperamental distress to limitations and African American ethnicity were associated with reduced cortisol reactivity. Findings are consistent with prior work linking early caregiving to the development of the hypothalamic-pituitary-adrenal axis stress response system and with a conceptual model in which developing temperament is characterized by the interplay of emotional reactivity and the emergence of the ability to effortfully regulate this reactivity using attention.     

Emotions: From neuropsychology to functional imaging

Recent developments in functional imaging techniques, such as Positron Emission Tomography (PET) and functional Magnetic Resonance Imaging (fMRI), allow us to characterize more precisely the functional neuroanatomy mediating emotional responding. This corpus of studies has led to the development of affective neuroscience. First, we present a summary of the studies aimed at understanding the underlying mechanisms of the emotional response, which were conducted prior to the use of the brain imaging techniques. Then, this paper reviews the studies investigating the neural substrates implicated in the processing of facial expressions and those implicated in the production of experimentally induced emotional responses. This review of the literature includes a meta‐analysis of eight studies using PET and one fMRI study reporting the neural correlates of experimentally induced emotions in healthy individuals. The methods and results of these studies are described through figures drawn from the reported Talairach's coordinates depicting the cerebral regions activated in relation to different experimental conditions. The implications of the results and the role of the cerebral structures that have been identified are discussed. As regards the studies on the neural bases of the processing of facial expressions of emotion, there are separable neural circuits that are involved in mediating responding to differing categories of facial expressions of emotion. Fearful expressions have relatively consistently been found to activate the amygdala, as, occasionally, have sad and happy expressions. The anterior insula and the putamen seem to be particularly involved in disgust expression recognition, whereas the facial expression of anger seems to be predominantly associated with anterior cingular and orbitofrontal cortex activity. Among the cerebral structures that have appeared to be activated by experimentally induced emotions, the anterior cingulate cortex seems to play a specific role in representing subjective emotional responses.     

The Interaction of Mood and Rumination in Depression: Effects on Mood Maintenance and Mood-Congruent Autobiographical Memory

Rumination is a response to distress in which individuals focus repetitively on their feelings and the causes and consequences of those feelings. When induced to ruminate, dysphorics exhibit more negative mood and recall more negative memories, but these effects are not seen in nondysphorics. This pattern of results could be due to trait-like differences between dysphoric and nondysphoric individuals, or to the high levels of negative affect that dysphorics are experiencing at the time of rumination. The purpose of this study was to evaluate the effects of pre-rumination mood on post-rumination mood and subsequent memory. Participants scoring high or low in depressive symptoms were assigned to either a positive or negative emotion induction prior to ruminating and completing an autobiographical memory task. Analysis of self-reported mood indicates that both emotion inductions were effective. Surprisingly, all participants returned to baseline mood levels following the rumination induction, and emotion induction had no effect on the negativity of the memories recalled. Dysphorics recalled significantly more negative memories than nondysphorics, regardless of whether positive, neutral, or negative memories were specifically prompted. Our results indicated that the prolonged experience of dysphoria may have greater effects on post-rumination mood and memory than the transitory experience of sadness.     

Developmental shifts in fMRI activations during visuospatial relational reasoning

To investigate maturational plasticity of fluid cognition systems, functional brain imaging was undertaken in healthy 8-19 year old participants while completing visuospatial relational reasoning problems similar to Raven's matrices and current elementary grade math textbooks. Analyses revealed that visuospatial relational reasoning across this developmental age range recruited activations in the superior parietal cortices most prominently, the dorsolateral prefrontal, occipital-temporal, and premotor/supplementary cortices, the basal ganglia, and insula. There were comparable activity volumes in left and right hemispheres for nearly all of these regions. Regression analyses indicated increasing activity predominantly in the superior parietal lobes with developmental age. In contrast, multiple anterior neural systems showed significantly less activity with age, including dorsolateral and ventrolateral prefrontal, paracentral, and insula cortices bilaterally, basal ganglia, and particularly large clusters in the midline anterior cingulate/medial frontal cortex, left middle cingulate/supplementary motor cortex, left insula-putamen, and left caudate. Findings suggest that neuromaturational changes associated with visuospatial relational reasoning shift from a more widespread fronto-cingulate-striatal pattern in childhood to predominant parieto-frontal activation pattern in late adolescence.
