An electrophysiological dissociation of craving and stimulus-dependent attentional capture in smokers

It has been suggested that over the course of an addiction, addiction-related stimuli become highly salient in the environment, thereby capturing an addict’s attention. To assess these effects neurally in smokers, and how they interact with craving, we recorded electroencephalography (EEG) in two sessions: one in which participants had just smoked (non-craving), and one in which they had abstained from smoking for 3 h (craving). In both sessions, participants performed a visual-search task in which two colored squares were presented to the left and right of fixation, with one color being the target to which they should shift attention and discriminate the locations of two missing corners. Task-irrelevant images, both smoking-related and non-smoking-related, were embedded in both squares, enabling the shift of spatial attention to the target to be examined as a function of the addiction-related image being present or absent in the target, the distractor, or both. Behaviorally, participants were slower to respond to targets containing a smoking-related image. Furthermore, when the target contained a smoking-related image, the neural responses indicated that attention had been shifted less strongly to the target; when the distractor contained a smoking-related image, the shift of attention to the contralateral target was stronger. These effects occurred independently of craving and suggest that participants were actively avoiding the smoking-related images. Together, these results provide an electrophysiological dissociation between addiction-related visual-stimulus processing and the neural activity associated with craving.     

What do memory data tell us about the role of contingency awareness in evaluative conditioning?

Evaluative conditioning (EC) refers to the effect that pairings of a conditioned stimulus (CS) with a valenced unconditioned stimulus (US) lead to changes in the evaluation of the CS. There have been recurring debates about whether EC requires awareness of the contingency between CSs and USs during learning. We argue that the memory performance data obtained in the standard paradigm remain ambiguous about the role of contingency awareness during the encoding of CS–US pairings. First, memory performance data are unable to distinguish between encoding-related versus retrieval-related effects. Second, the relation between memory performance and evaluation is correlational, which limits conclusions about causal relations between memory performance and EC effects. These ambiguities imply that any possible data pattern can be interpreted in at least two different ways. It is concluded that a resolution of the current debate requires alternative approaches in which contingency awareness is experimentally manipulated during the encoding of CS–US pairings.     

On the intentional control of conditioned evaluative responses

The evaluative conditioning (EC) effect is defined as a change in the evaluation of a conditioned stimulus (CS) due to its pairing with a valenced unconditioned stimulus (US). The current research investigated the controllability of EC effects by asking participants to either promote or prevent the influence of CS–US pairings before they provided evaluative ratings of the CS. Experiment 1 showed that instructions to maximize or minimize the influence of CS–US pairings moderated EC effects in line with task instructions. However, this moderation was observed only when participants were able to recall the valence of the US that had been paired with a given CS. When participants failed to remember the valence of the US, significant EC effects emerged regardless of control instructions. Experiment 2 tested whether the influence of CS–US pairings on CS evaluations can be intentionally reversed. The results showed that reversal instructions led to a reverse EC effect when participants were able to recall the valence of the US that had been paired with a given CS, but not when they were unable to recall the valence of the US. Taken together, these results suggest that US valence memory is a necessary precondition for controlling the expression of a conditioned evaluative response, but it is not a necessary precondition for the emergence of EC effects per se.     

Changing likes and dislikes through the back door: The US-revaluation effect

US-revaluation refers to the observation that subsequent changes in the valence of an unconditioned stimulus (US) after pairing it with a neutral, conditioned stimulus (CS) also changes the valence of the associated CS. Experiment 1 found evidence for the US-revaluation effect using an unobtrusive measure of evaluation. However, US-revaluation effects were more pronounced for positive-to-negative compared to negative-to-positive revaluations. Experiment 2 replicated this finding for self-reported evaluations, further showing that US-revaluation effects are stable over time and independent of explicit memory for the revaluating information. Using a modified paradigm, Experiment 3 ruled out method-related explanations for these findings and showed that changes in CS evaluations are correlated with parallel changes in US evaluations. These findings encourage the view of evaluative conditioning as an instance of stimulus–stimulus (S–S) rather than stimulus-response (S–R) learning. Implications for basic and applied research are discussed.     

A functional-cognitive framework for attitude research

In attitude research, behaviours are often used as proxies for attitudes and attitudinal processes. This practice is problematic because it conflates the behaviours that need to be explained (explanandum) with the mental constructs that are used to explain these behaviours (explanans). In the current chapter we propose a meta-theoretical framework that resolves this problem by distinguishing between two levels of analysis. According to the proposed framework, attitude research can be conceptualised as the scientific study of evaluation. Evaluation is defined not in terms of mental constructs but in terms of elements in the environment, more specifically, as the effect of stimuli on evaluative responses. From this perspective, attitude research provides answers to two questions: (1) Which elements in the environment moderate evaluation? (2) What mental processes and representations mediate evaluation? Research on the first question provides explanations of evaluative responses in terms of elements in the environment (functional level of analysis); research on the second question offers explanations of evaluation in terms of mental processes and representations (cognitive level of analysis). These two levels of analysis are mutually supportive, in that better explanations at one level lead to better explanations at the other level. However, their mutually supportive relation requires a clear distinction between the concepts of their explanans and explanandum, which are conflated if behaviours are treated as proxies for mental constructs. The value of this functional-cognitive framework is illustrated by applying it to four central questions of attitude research.     

“Short-Form” Content Scales for the MMPI

Using an abbreviated version of content scales derived by a rational-theoretical approach to the MMPI item pool rather than the traditional criterion group approach, this report demonstrates both satisfactory long- short-form correlations and promising internal consistency for these short-form scales. Comparing women discharged from a psychiatric hospital (N = 40) and non-psychiatric controls (N = 41), these content scales differentiate the two groups both at the beginning of an aftercare intervention study and approximately 20 months later. Mood scales are somewhat less stable over time, especially among patients. While not correlated with age or verbal intelligence, several scales are correlated with measures of social status.     

Pathogenesis: A New Therapist Personality Dimension Related to Therapeutic Effectiveness

The pre-project TATs of ten therapists were rated for “pathogenesis” and these ratings later correlated with their patient's level of functioning after six months of treatment. Outcome was measured in a variety of data modalities: intellectual tests, thought disorder measures, projectives, clinical status interviews, and hospitalization. Significant correlations were obtained on five of eight outcome measures. Patients of more benign (or less pathogenic) therapists demonstrated greater foresight, less schizophrenic thought disorder, greater intellectual functioning, were rated as healthier in the Clinical Status Interview, and spent less time in the hospital than patients of more pathogenic therapists.     

Innovating With the Model of Human Occupation in Mental Health

This article describes a new approach in a group of National Health Service trusts in the United Kingdom. The assessment and intervention were focused on using the Model of Human Occupation in Mental Health services. An occupation focused assessment and intervention protocol were developed based on the Model of Human Occupation Screening Tool Single-Observation Form (MOHOST-SOF). The aim was to develop a guide to treatment and monitoring to support efficient practice while maintaining an occupation and client-centered focus. Implementation has been successful to date.     

Psychopathy,unconscious shame and attachment: Considering the psychodynamics of psychopathy

Recent psychopathy research has involved a critical re-examination of the construct. Absent from this research has been an analysis of the role unconscious shame might play in etiology, traits and behaviour. Outside of the domain of psychopathy research, the significant role shame plays in intra- and interpersonal dynamics has been comprehensively investigated for the past few decades. More recently, exploration into the role that attachment plays in the development of shame has been suggested. The extant shame literature has explored the connection between unconscious shame and a range of behaviours, many of which are characteristic of psychopathy. While there have been some investigations on the association between psychopathy and conscious shame, this paper suggests that the exploration of unconscious shame, and its development resulting from certain attachment dynamics, can potentially further enhance our conceptualisation of psychopathy with regard to etiology, traits, behaviour, assessment and treatment. After reviewing the literature on unconscious shame, attachment and psychopathy, recommendations for future research are suggested.
