Do self‐presentation concerns moderate the relationship between implicit and explicit homonegativity measures?

This study investigated whether the relation between implicit and explicit homonegativity measures is affected by self-presentation concerns, since previous research in this area has been inconclusive. In Experiment 1, 70 high-school students made evaluative ratings of pictures of homosexual and heterosexual couples. Self-presentation was manipulated by either instructing participants that the study concerned attitudes regarding sexual orientation (socially sensitive) or attitudes regarding age (less sensitive). The age-instruction led to increased homonegativity but not to a stronger correlation with an Implicit Association Test (IAT; Greenwald, McGhee & Schwartz, 1998) with homo/heterosexual couples. Concerns regarding the construct validity of the present implementation of the IAT were alleviated in Experiment 2, where heterosexual (n= 30) but not homosexual (n= 30) participants showed implicit homonegativity. The current findings are problematic for the interpretation of low correspondence between implicit and explicit attitude measures as being primarily an effect of self-presentation concerns.     

Risky decision making across three arenas of choice: are younger and older adults differently susceptible to framing effects?

In the present study, the authors investigated the effects of framing of options on risky decision making in groups of younger adults (M = 23.8 years, n = 192) and older adults (M = 69.1 years, n = 192). The participants were assigned to one of three scenarios varying in the goods at stake (human lives, paintings, money). The authors observed a majority preference in favor of the risky options after negative, but not positive framing. They also found, as they had predicted, that the type of framing effect varied across scenarios, with a bidirectional framing effect for the life-death scenario and unidirectional (risk averse) framing effects when public property (paintings) or personal property (money) were at stake. It is important to note that these choice preference patterns were highly similar across the age groups, which reinforced the conclusion that younger and older adults are equally susceptible to framing effects.     

Perfectionism, self-consciousness and anxiety

The relation between perfectionism, anxiety, and self-consciousness was studied in a normal sample. The perfectionism dimensions of Concern over Mistakes, Doubts about Action, and Socially Prescribed Perfectionism showed a pattern of correlations not only with measures of social anxiety, but also with measures of agoraphobic fears, and fears of bodily injury, death and illness. Public self-consciousness also correlated with various measures of anxiety, but these correlations disappeared when the relevant dimensions of perfectionism were controlled for. It is concluded that perfectionism is a more relevant construct in the study of anxiety than is public self-consciousness. The results are discussed in terms of possible causal relationships between perfectionism and anxiety.     

Belief revision,epistemic conditionals and the Ramsey test

Epistemic conditionals have often been thought to satisfy the Ramsey test (RT): If A, then B is acceptable in a belief state G if and only if B should be accepted upon revising G with A. But as Peter Gärdenfors has shown, RT conflicts with the intuitively plausible condition of Preservation on belief revision. We investigate what happens if (a) RT is retained while Preservation is weakened, or (b) vice versa. We also generalize Gärdenfors' approach by treating belief revision as a relation rather than as a function.In our semantic approach, the same relation is used to model belief revision and to give truth-conditions for conditionals. The approach validates a weak version of the Ramsey Test (WRR) — essentially, a restriction of RT to maximally consistent belief states.We prove that alternatives (a) and (b) are both consistent, but argue that (b) is philosophically more promising. Gärdenfors' belief-revision axioms are compatible with WRR together with RT from left to right: the only direction of the test that is defensible on intuitive grounds.An earlier version of this paper was presented at the conference on the dynamics of knowledge and belief at Lund University, 24–26 August 1989. We wish to thank Sven Danielsson, Peter Gärdenfors, Sören Halldén, David Makinson, Hugh Mellor, Michael Morreau, Nils-Eric Sahlin and Brian Skyrms for their very helpful suggestions and remarks. We are also grateful for thought-provoking criticism and comments from two anonymous referees.     

An after-effect in haptic space perception

After-effects in haptic perception have been little studied. But they seem to be prominent, and easy to elicit. An after-effect of the perception of the vergence of two surfaces is described, and is shown to be independent of the slant of the surfaces. It is not “figural.” Spatial perception with the hands, as well as with the eyes, is apparently based on a fluid and adaptable receptive system.     

A VERSATILE EYE-MOVEMENT RECORDER

A small, light eye-movement recorder, capable of registering eye movements from the smallest voluntary movements to movements of 20 degrees of arc, is described. A miniature light projector gives a beam of infrared (or blue) light, which is reflected by the cornea of the eye. The beam is deflected by any movement of the eye. An optical system transforms the motion of the beam into changes of light intensity. These are translated into magnified fluctuations of current in a multiplier phototube. The output is translated into graphic form by an ink-writer fitted with a D.C. amplifier. The apparatus, except for the writer but including a helmet, weighs about 300–500 g and is mounted on the subject's head without appreciably disturbing the field of vision.     

A learning theory account of depression

Learning theory provides a foundation for understanding and deriving treatment principles for impacting a spectrum of functional processes relevant to the construct of depression. While behavioral interventions have been commonplace in the cognitive behavioral tradition, most often conceptualized within a cognitive theoretical framework, recent years have seen renewed interest in more purely behavioral models. These modern learning theory accounts of depression focus on the interchange between behavior and the environment, mainly in terms of lack of reinforcement, extinction of instrumental behavior, and excesses of aversive control, and include a conceptualization of relevant cognitive and emotional variables. These positions, drawn from extensive basic and applied research, cohere with biological theories on reduced reward learning and reward responsiveness and views of depression as a heterogeneous, complex set of disorders. Treatment techniques based on learning theory, often labeled Behavioral Activation (BA) focus on activating the individual in directions that increase contact with potential reinforcers, as defined ideographically with the client. BA is considered an empirically well‐established treatment that generalizes well across diverse contexts and populations. The learning theory account is discussed in terms of being a parsimonious model and ground for treatments highly suitable for large scale dissemination.     

Improved resiliency and well‐being among military personnel in a Swedish Naval Force after a counter‐piracy operation off the coast of Somalia

The aim of this study was to explore: (1) how the psychological health of the members of the first European Union Naval Force (ME01) was affected by international deployment off the coast of Somalia; and (2) if and how organizational and personal factors (e.g., type of personnel category, previous experiences, and resilience) affected their psychological health and well‐being post‐deployment. The study had an exploratory longitudinal design, where the participants were assessed both before and after deployment (i.e., T1 and T2). The participants (n = 129, 120 men, 9 women) were equally distributed between officers (n = 68; 64 men, 4 women) and sailors (n = 61; 56 men, 5 women). The members' average age was 31 years, ranging from 20 to 61. For the majority (78%) ME01 was their first international deployment and officers were, in general, more experienced than sailors. The overall results showed that the members' reported a positive experience with improved resilience and well‐being (e.g., sense of coherence). However, the result also showed that type of personnel category (i.e., officer or sailor) affected their psychological health. Why and how these differences among military personnel arise is discussed, but deserves further attention.

Using time‐lagged panel data analysis to study mechanisms of change in psychotherapy research: Methodological recommendations

The introduction of novel methodologies in the past decade has advanced research on mechanisms of change in observational studies. Time‐lagged panel models allow us to track session‐by‐session changes and focus on within‐patient associations between predictors and outcomes. This shift is crucial as change in mechanisms inherently takes place at a within‐patient level. These models also enable preliminary casual inferences, which can guide the development of effective personalised interventions that target mechanisms of change, used at specific treatment phases for optimal effect. Given their complexity, panel models need to be implemented with caution, as different modelling choices can significantly affect results and reduce replicability. We outline three central methodological recommendations for use of time‐lagged panel analysis to study mechanisms of change: (a) taking patient‐specific effects into account, separating out stable between‐person differences from within‐person fluctuations over time; (b) properly controlling for autoregressive effects; and (c) considering long‐term time trends. We demonstrate these recommendations in an applied example examining the session‐by‐session alliance–outcome association in a naturalistic psychotherapy study. We present limitations of time‐lagged panel analysis and future directions.
