The generation and maintenance of visual mental images: evidence from image type and aging

Imagery is a multi-componential process involving different mental operations. This paper addresses whether separate processes underlie the generation, maintenance and transformation of mental images or whether these cognitive processes rely on the same mental functions. We also examine the influence of age on these mental operations for independence of components. In Experiment 1, younger (22 years) and older (69 years) adults generated and maintained general, specific, contextual and autobiographical visual mental images evoked in response to concrete nouns. The older adults had longer generation times, but there was no difference between the two groups on maintenance. Both groups had shortest generation and maintenance times for general images, whereas only the older adults took longest in generating autobiographical images. In Experiment 2, the total maintenance time and number of transformations for each type of image were compared in another group of younger and older adults. General images were less transformed and more subject to decay for both groups. The older people maintained the autobiographical mental images for longest compared to other image types. In conclusion, image generation, maintenance and transformation seem to be differently affected by type of image and aging, supporting a model of their cognitive segregation.     

Task unrelated thought whilst encoding information

Task unrelated thought (TUT) refers to thought directed away from the current situation, for example a daydream. Three experiments were conducted on healthy participants, with two broad aims. First, to contrast distributed and encapsulated views of cognition by comparing the encoding of categorical and random lists of words (Experiments One and Two). Second, to examine the consequences of experiencing TUT during study on the subsequent retrieval of information (Experiments One, Two, and Three). Experiments One and Two demonstrated lower levels of TUT and higher levels of word-fragment completion whilst encoding categorical relative to random stimuli, supporting the role of a distributed resource in the maintenance of TUT. In addition the results of all three experiments suggested that experiencing TUT during study had a measurable effect on subsequent retrieval. TUT was associated with increased frequency of false alarms at retrieval (Experiment One). In the subsequent experiments TUT was associated with no advantage to retrieval based on recollection, by manipulating instructions at encoding (Experiment Two), and/or at retrieval (Experiment Three). The implications of the results of all three experiments are discussed in terms of recent accounts of memory retrieval and conscious awareness.     

The Perception of the Other in International Relations: Evidence for the Polarizing Effect of Entitativity

In an international relations context, the mutual images held by actors affect their mutual expectations about the Other's behavior and guide the interpretation of the Other's actions. Here it is argued that the effect of these images is moderated by the degree of entitativity of the Other—that is, the extent to which it is perceived as a real entity. Two studies tested this hypothesis by manipulating the entitativity of the European Union (EU) among U.S. citizens whose images of the EU varied along the enemy/ally dimension. Results of these studies yielded converging evidence in support of the hypothesized moderating effect of entitativity. Specifically, entitativity showed a polarizing effect on the relationship between the image of the EU and judgments of harmfulness of actions carried out by the EU.     

Time course of the Simon effect in pointing movements for horizontal, vertical, and acoustic stimuli: evidence for a common mechanism

In the Simon effect, responses to a non-spatial attribute are faster when the irrelevant spatial position of the stimulus corresponds to the position of the response. It was suggested that there are two distinct mechanisms involved in the Simon effect. In the visuomotor Simon effect, the stimulus transiently activates the corresponding response which results in a decaying Simon effect function (i.e., the Simon effect decreases in slower reaction time [RT]-bins). In contrast, the cognitive Simon effect arises from a conflict between stimulus and response codes and is associated with a stable Simon effect function (i.e., the Simon effect is the same in fast and slow RT-bins). We recorded RTs and motor parameters of pointing movements in a Simon paradigm. Consistent with the previous research, the time course of the Simon effect in RTs was stable with vertical visual and horizontal acoustic stimuli (cognitive Simon tasks), but decreased with horizontal visual stimuli (visuomotor Simon task). In contrast, the Simon effect in motor parameters decreased across RT-bins in all conditions, supporting the idea that only a single, common mechanism underlies the Simon effect.     

Is amenorrhea a clinically useful criterion for the diagnosis of anorexia nervosa?

Aim of the study was to evaluate the clinical characteristics and the treatment outcome of underweight patients with eating disorder (ED) not otherwise specified without amenorrhea (EDNOS-WA), compared with classical anorexia nervosa (AN) cases. Seventy-three consecutive female patients (57 AN, and 16 EDNOS-WA) were evaluated before and after a 20-week cognitive behaviour inpatient treatment (CBT-I). Assessment included anthropometry, the Eating Disorder Examination (EDE), the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and the Temperament and Character Inventory (TCI). At logistic regression analysis, amenorrhea was only predicted by baseline BMI and intense exercise, not by psychopathological variables. Response to CBT-I was good and similar between groups, without differences in the dropout rate or time-to-dropout. Our data lend support to the hypothesis that the criterion “amenorrhea” is of no clinical utility in the diagnosis and treatment of AN and could be removed in the forthcoming DSM-V proposal.     

Group psychodynamic counselling with final-year undergraduates in clinical psychology: A clinical methodology to reinforce academic identity and psychological well-being

Educational institutions should ensure that students develop a professional identity, as well as safeguarding their well-being and activating awareness and change processes. The aim of this study was to assess the efficacy of group psychodynamic counselling as a means of reinforcing academic identity – considered the forerunner of professional identity – and psychological well-being in a group of final-year undergraduates studying clinical psychology. Thirty-three final-year-students of clinical psychology who participated in six group psychodynamic counselling sessions were compared with sixteen final-year students of clinical psychology who had never participated in an intervention of this kind. The results suggested that group psychodynamic counselling made students feel more capable of managing their lives and more open to new experiences as well as encouraging them to perceive their relationships as more positive and satisfying, to believe that their life is meaningful, and to achieve greater self-acceptance. The in-depth exploration also prompted students to consider their commitment to their choice of career. Group psychodynamic counselling also reinforced students’ educational choice, as the likelihood of students becoming less committed to this choice was reduced after the intervention. Thus, the study confirmed the efficacy of group psychodynamic counselling as a means of reinforcing both academic identity and promoting well-being and demonstrated that it is a tool clinical psychologists and university teachers could use to activate self-reflection and change within educational settings.     

Identity Statuses and Event-Focused Narratives at University Starting Point in Italy

The purpose of this study was to explore in greater depth the identity formation processes in Italian university students starting from previous studies that have provided support for a “postponed Identity”. Given the particular socio-economic difficulties of the Italian context, especially occupational uncertainty, this study assumes that the years of university for Italian students are rather like a time of standby, a period when students are allowed to remain in moratorium (institutionalized) or diffusion statuses and disengage from tasks related to personal and professional identity consolidation. For this purpose, the study focuses initially on the person-centred approach by measuring identity statuses in students attending the first 2 years of university and in students attending the fourth and fifth years of university. Subsequently, it focuses on the first 2 years of university through an event-focused approach, exploring narrative accounts of memorable daily life events perceived as important for identity construction, and to deepen our understanding of the subjective dimension of personal changes. Based on five identity dimensions, the cluster analysis indicated that six identity statuses could be extracted for both students groups: achievement, foreclosure, moratorium, diffused diffusion, carefree diffusion and undifferentiated. Each of these clusters revealed a distinct profile in terms of narrative universes of meaning. The study explored associations between narratives, reflecting a particular focus on the identity content and identity statuses. Suggestions for future research and limitations are discussed.     

Rumination and social problem-solving in depression

We tested the hypothesis that impaired social problem solving in depression is a consequence of state-oriented rumination, which can be ameliorated by improving awareness of mental processes. 32 currently depressed, 26 recovered depressed, and 26 never depressed participants completed the Means Ends Problem Solving Test while randomly allocated to no questions, state-oriented ruminative questions, (e.g. focusing on why you have a problem) or process-focused questions (e.g. focusing on how you decide to solve a problem). In the no question condition, the currently depressed group was significantly impaired at problem solving compared to the never depressed and recovered depressed groups, which did not differ from each other. As predicted, the process-focused questions significantly improved social problem solving in depressed patients, compared to no questions and state-oriented questions, which did not differ from each other. As predicted, compared to the process-focused questions, the state-oriented questions significantly impaired social problem solving in the recovered depressed group. These results are consistent with recent theories and treatment developments which suggest that increased awareness of mental processes can shift people away from ruminative thinking, thereby, reducing depressive relapse.     

Confirming expectations in asymmetric and symmetric social hypothesis testing

This article examines individuals' expectations in a social hypothesis testing task. Participants selected questions from a list to investigate the presence of personality traits in a target individual. They also identified the responses that they expected to receive and the likelihood of the expected responses. The results of two studies indicated that when people asked questions inquiring about the hypothesized traits that did not entail strong a priori beliefs, they expected to find evidence confirming the hypothesis under investigation. These confirming expectations were more pronounced for symmetric questions, in which the diagnosticity and frequency of the expected evidence did not conflict. When the search for information was asymmetric, confirming expectations were diminished, likely as a consequence of either the rareness or low diagnosticity of the hypothesis-confirming outcome. We also discuss the implications of these findings for confirmation bias.
