Lay understandings of defence mechanisms: The role of personality traits and gender

This study looks at lay people's knowledge and use of the defence mechanisms. It focused on 21 of the better known "Freudian" defence mechanisms. A total of 208 participants (73 males and 135 females) completed a questionnaire regarding their knowledge and reported personal use of 21 defence mechanisms and a short personality test. Participants were required to state (1) whether they had heard of each mechanism, (2) how common they believed it to be and (3) whether they themselves used each of them. The defences were categorised into four levels: Pathological, immature, neurotic and mature. Two personality traits (Openness and Neuroticism) positively correlated with two of the levels but few gender or age correlations were identified. Regression analysis showed that Neuroticism predicted the three less mature defence levels; Gender was a contributing predictor of a pathological defence style and Openness and religiosity combined with Neuroticism predicted an immature defence style. Participants admitted using the more socially acceptable (mature) defences (i.e. humour, intellectualisation) than the less acceptable (pathological) defences (i.e. distortion, hypochondriasis). Implications for psychotherapy are discussed and the limitations of the study considered.     

Perceptions of physical and psychological aggression in close relationships: A review

This review of the literature examines the effect of contextual variables (i.e., characteristics of the perpetrator and victims, observer characteristics) on perceptions of physical and psychological aggression in close relationships. Observers view physical aggression as more serious, harmful, abusive, and more deserving of punishment than psychological aggression, male aggression as more serious than female aggression, and aggression in committed, exclusive relationships as more serious than aggression in casual ones. Victims of psychological aggression, however, perceive it as more harmful than physical aggression and consider the effects to be longer-lasting. The disparity between observer and victim perceptions of physical and psychological aggression extends to mental health professionals, who tend to judge the severity of aggressive behaviors based on frequency and duration of the actions instead of perpetrator intent. This difference of opinion may influence the reporting of and intervention in physically or psychologically aggressive situations, and how these types of aggression are treated by legal professionals, especially if those legal professionals are informed about aggressive romantic relationships by third-party observers whose opinions of the situation differ from those of the victims.     

Sex differences in estimating multiple intelligences in self and others: A replication in Russia

This was a crosscultural study that focused on sex differences in self‐ and other‐estimates of multiple intelligences (including 10 that were specified by Gardner, 1999 and three by Sternberg, 1988) as well as in an overall general intelligence estimate. It was one of a programmatic series of studies done in over 30 countries that has demonstrated the female “humility” and male “hubris” effect in self‐estimated and other‐estimated intelligence. Two hundred and thirty Russian university students estimated their own and their parents’ overall intelligence and “multiple intelligences.” Results revealed no sex difference in estimates of overall intelligence for both self and parents, but men rated themselves higher on spatial intelligence. This contradicted many previous findings in the area which have shown that men rate their own overall intelligence and mathematical intelligence significantly higher than do women. Regressions indicated that estimates of verbal, logical, and spatial intelligences were the best predictors of estimates of overall intelligence, which is a consistent finding over many studies. Regressions also showed that participants’ openness to experience and self‐respect were good predictors of intelligence estimates. A comparison with a British sample showed that Russians gave higher mother estimates, and were less likely to believe that IQ tests measure intelligence. Results were discussed in relation to the influence of gender role stereotypes on lay conception of intelligence across cultures.     

A facial expression for anxiety

Anxiety and fear are often confounded in discussions of human emotions. However, studies of rodent defensive reactions under naturalistic conditions suggest anxiety is functionally distinct from fear. Unambiguous threats, such as predators, elicit flight from rodents (if an escape-route is available), whereas ambiguous threats (e.g., the odor of a predator) elicit risk assessment behavior, which is associated with anxiety as it is preferentially modulated by anti-anxiety drugs. However, without human evidence, it would be premature to assume that rodent-based psychological models are valid for humans. We tested the human validity of the risk assessment explanation for anxiety by presenting 8 volunteers with emotive scenarios and asking them to pose facial expressions. Photographs and videos of these expressions were shown to 40 participants who matched them to the scenarios and labeled each expression. Scenarios describing ambiguous threats were preferentially matched to the facial expression posed in response to the same scenario type. This expression consisted of two plausible environmental-scanning behaviors (eye darts and head swivels) and was labeled as anxiety, not fear. The facial expression elicited by unambiguous threat scenarios was labeled as fear. The emotion labels generated were then presented to another 18 participants who matched them back to photographs of the facial expressions. This back-matching of labels to faces also linked anxiety to the environmental-scanning face rather than fear face. Results therefore suggest that anxiety produces a distinct facial expression and that it has adaptive value in situations that are ambiguously threatening, supporting a functional, risk-assessing explanation for human anxiety.     

Saccade launch site as a predictor of fixation durations in reading: comments on Hand, Miellet, O'Donnell, and Sereno (2010)

An important question in research on eye movements in reading is whether word frequency and word predictability have additive or interactive effects on fixation durations. A fair number of studies have reported only additive effects of the frequency and predictability of a target word on reading times on that word, failing to show significant interactions. Recently, however, Hand, Miellet, O'Donnell, and Sereno (see record 2010-19099-001) reported interactive effects in a study that included the distance of the prior fixation from the target word (launch site). They reported that when the saccade into the target word was launched from very near to the word (within 3 characters), the predictability effect was larger for low frequency words, but when the saccade was launched from a medium distance (4-6 characters from the word) the predictability effect was larger for high frequency words. Hand et al. argued for the importance of including launch site in analyses of target word fixation durations. Here we describe several problems with Hand et al.'s use of analyses of variance in which launch site is divided into distinct ordinal levels. We describe a more appropriate way to analyze such data-linear mixed-effect models-and we use this method to show that launch site does not modulate the interaction between frequency and predictability in two other data sets.     

The distribution of fixation durations during reading: effects of stimulus quality

Participants' eye movements were recorded as they read single sentences presented normally, presented entirely in faint text, or presented normally except for a single faint word. Fixations were longer when the entire sentence was faint than when the sentence was presented normally. In addition, fixations were much longer on a single faint word embedded in normal text, compared to when the entire sentence was faint. The primary aim of the study was to examine the influence of stimulus quality on the distribution of fixation durations. Ex-Gaussian fitting revealed that stimulus quality affected the mean of the Normal component, but in contrast to results from single-word tasks (Plourde & Besner, 1997), stimulus quality did not affect the exponential component, regardless of whether one or all words were faint. The results also contrast with the finding (Staub, White, Drieghe, Hollway, & Rayner, 2010) that the word frequency effect on fixation durations is an effect on both of the critical distributional parameters. These findings are argued to have implications for the interpretation of the role of stimulus quality in word recognition, and for models of eye movement control in reading.     

Metacognitive therapy in treatment-resistant depression: a platform trial

Patients with treatment-resistant depression received up to 8 sessions of metacognitive therapy (MCT) targeting attentional control, rumination, worry, and metacognitive beliefs. A baseline period was followed by weekly sessions with follow-up assessments at 6 and 12 months post treatment. Large and statistically significant improvements occurred in all symptom measures at post treatment and were maintained over follow-up. Two out of 3 process measures significantly improved at post treatment and all of these measures were improved at follow-up. Treatment was associated with similar response rates on the BDI and Hamilton rating scale. Using liberal criteria 80% of completers were classified as recovered at post treatment and 70% at follow-up on the BDI. In the intention to treat sample 66.6% were recovered at post treatment and 58.3% at follow-up. More stringent criteria showed 60% recovery rates at post treatment and at 12 m. The results suggest that MCT could be a brief and effective treatment and they provide a precedent for more definitive randomized controlled trials.     

The effect of background music on the taste of wine

Research concerning cross-modal influences on perception has neglected auditory influences on perceptions of non-auditory objects, although a small number of studies indicate that auditory stimuli can influence perceptions of the freshness of foodstuffs. Consistent with this, the results reported here indicate that independent groups' ratings of the taste of the wine reflected the emotional connotations of the background music played while they drank it. These results indicate that the symbolic function of auditory stimuli (in this case music) may influence perception in other modalities (in this case gustation); and are discussed in terms of possible future research that might investigate those aspects of music that induce such effects in a particular manner, and how such effects might be influenced by participants' pre-existing knowledge and expertise with regard to the target object in question.     

Perspective-taking and depth of theory-of-mind reasoning in sequential-move games

Theory-of-mind (ToM) involves modeling an individual's mental states to plan one's action and to anticipate others' actions through recursive reasoning that may be myopic (with limited recursion) or predictive (with full recursion). ToM recursion was examined using a series of two-player, sequential-move matrix games with a maximum of three steps. Participants were assigned the role of Player I, controlling the initial and the last step, or of Player II, controlling the second step. Appropriate for the assigned role, participants either anticipated or planned Player II's strategy at the second step, and then determined Player I's optimal strategy at the first step. Participants more readily used predictive reasoning as Player II (i.e., planning one's own move) than as Player I (i.e., anticipating an opponent's move), although they did not differ when translating reasoning outcome about the second step to optimal action in the first step. Perspective-taking influenced likelihood of predictive reasoning, but it did not affect the rate at which participants acquired it during the experimental block. We conclude that the depth of ToM recursion (related to perspective-taking mechanisms) and rational application of belief-desire to action (instrumental rationality) constitute separate cognitive processes in ToM reasoning.
