Inhibitory Control and Working Memory in Post-Institutionalized Children

Inhibitory control and working memory were examined in post-institutionalized (PI) children adopted into United States families from Russian institutions. The PI sample originated from institutions that were less severely depriving than those represented in previous studies and approximated the level of psychosocial deprivation, which is characterized by adequate physical resources but a lack of consistent and responsive caregiving. PI children (N?=?75; 29 male) ranged in age from 8–17 years (M?=?12.97; SD?=?3.03) and were grouped according to whether they were adopted after 14 months or before 9 months. A non-adopted comparison group (N?=?133; 65 male) ranged in age from 8–17 years (M?=?12.26; SD?=?2.75). PI children adopted after 14 months of age displayed poorer performance on the stop-signal and spatial span tasks relative to PI children adopted before 9 months of age after controlling for age at assessment. The two PI groups did not differ in their performance on a spatial self-ordered search task. Older-adopted PI children also showed poorer spatial span task performance compared to non-adopted children, but younger-adopted PI children did not. Task performance was significantly associated with parent-rated hyperactive-impulsive behavior in everyday contexts. These findings suggest that exposure to prolonged early institutional deprivation may be linked with inhibitory control and working memory difficulties years after adoption.     

The role of emotions arising from instability in investment behaviour / El papel de la carga emocional de la inestabilidad en el comportamiento de inversión

Abstract

Clear empirical evidence has been found on how significant changes to a person’s environment can alter their behaviour. This is important when considering investments made on the stock exchange as the variations that occur in stock market prices are frequent and continuous. This study analyses the role instability has on individual investors’ behaviour when investing in the stock market. The results suggest that instability in investment situations plays a significant role in individual investors’ behaviour, probably due to the emotional effect provoked by the possibility of suddenly losing savings. This would modify the perception investors have about investing as well as their intentions, attitudes and feelings of control in regards to investment in financial markets, thus hindering the capacity to predict their behaviour.     

Monitoring the source monitoring

The hypothesis that the retrieval of correct source memory cues, those leading to a correct source attribution, increases confidence, whereas the retrieval of incorrect source memory cues, those leading to a source misattribution, decreases confidence was tested. Four predictions were derived from this hypothesis: (1) confidence should be higher for correct than incorrect source attribution except; (2) when no source cues are retrieved; (3) only the source misattributions inferred from the retrieval of incorrect source cues will be rated with low confidence; and (4) the number of source cues retrieved, either correct or incorrect, will affect the confidence in the source attributions. To test these predictions, participants read two narratives from two witnesses to a bank robbery, a customer and a teller. Then, participants completed a source monitoring test with four alternatives, customer, teller, both, or neither, and rated their confidence in their source attribution. Results supported the first three predictions, but they also suggested that the number of correct source monitoring cues retrieved did not play a role in the monitoring of the accuracy of the source attributions. Attributions made from the recovery of incorrect source cues could be tagged as dubious or uncertain, thus leading to lowered confidence irrespective of the number of incorrect source cues or whether another correct source cue was also recovered. This research has potential applications for eyewitness memory because it shows that confidence can be an indicator of the accuracy of a source attribution.     

Bakhtin and Winnicott on dialogue,self, and cure

This paper develops a Bakhtinian dialogical perspective on the psychoanalytic discourse in general and on the concepts of true and false selves (Winnicott, 1960b) in particular. Bakhtin's assumptions about the origins of dialogicality in children's development are compared to Winnicott's ideas about the origins of true‐ and false‐self processes. This comparison leads to a characterization of the false and true selves as different genres of the narrated self—the epic and the novel—each with its specific configurations of experience and temporality. Moreover, psychoanalysis is conceived as a unique phenomenon that centers on the internal and most of the time simultaneous dialogues that take place in each of the two participants. This perspective underscores the impact of the analyst's subjectivity on the analytic process as well as the multiplicity of the patient's and the analyst's selves. In this context, therapeutic change can be seen most of the time as a transformation of genre and not necessarily as a modification of contents. Free association allows for the transgression of the basic rules of narrativity, thus facilitating a generic shift. A dialogical relation between the openness of free association and narrativity's coherence is suggested.

Life by its very nature is dialogic. To live means to participate in dialogue [Bakhtin, 1963, p. 293].

A word like “self”; naturally knows more than we do [Winnicott, 1960a, p. 158].     

Effects of Interest,Thematic Congruence,and Typicality on Memory for Television,Radio, and Press Advertisements of New Products

Little is known about how the content of advertisements is remembered. We studied how product interest, thematic congruence between advertisement and programme, and the typicality of the elements of an advertisement affect memory for new product ads in television, radio, and printed media. Participants were exposed to a single type of media with two embedded ads. After a filler task, they completed a true/false recognition task. In television and radio, accuracy was higher for the interesting product ads. In three experiments, we found no effect of thematic congruence, and the standard effect of typicality. In printed media, where participants are free to read the ads or not, the differences in hits and false alarms in typicality were due to a change in the response criterion and not to an effect on memory. We conclude that different results can be obtained depending on the exposure to different media. Copyright © 2015 John Wiley & Sons, Ltd.     

The free and cued selective reminding test: Validation for mild cognitive impairment and Alzheimer's disease

The International Working Group on Alzheimer's disease (AD) suggested the free and cued selective reminding test (FCSRT) to assess memory, as it showed high sensitivity and specificity in the differentiation of AD from healthy controls and other dementias. The FCSRT involves the use of selective reminding with semantic cueing in memory assessment. This study aims to validate the FCSRT for mild cognitive impairment (MCI) and AD through the analysis of the diagnostic accuracy and the suggestion of cut‐off scores. Patients were classified into two groups according to standard criteria: MCI (n = 100) and AD (n = 70). A matched control group (n = 101) of cognitively healthy subjects was included. The reliability and the validity of the FCSRT were analysed on the immediate (IR) and delayed (DR) recalls. The Cronbach's alpha was 0.915 for the IR and 0.879 for the DR. The total recall measures revealed good areas under the curve for MCI (IR: .818; DR: .828) and excellent for AD (IR: .987; DR: .991). Furthermore, the MCI group was subdivided with respect to a non‐similar/similar AD pattern of impairment, with almost half of the subjects showing an AD‐like decline. This analysis represents a novel contribution regarding the properties of the FCSRT in illustrating the heterogeneity of MCI at baseline. The FCSRT has proved to be a very useful tool in the characterization of the memory impairment of the AD spectrum.     

The benefits of retail therapy: Making purchase decisions reduces residual sadness

People often shop when feeling sad, but whether and why shopping reduces residual (lingering) sadness remains an open question. Sadness is strongly associated with a sense that situational forces control the outcomes in one's life, and thus we theorized that the choices inherent in shopping may restore personal control over one's environment and reduce residual sadness. Three experiments provided support for our hypothesis. Making shopping choices helped to alleviate sadness whether they were hypothetical (Experiment 1) or real (Experiment 2). In addition, all experiments found support for the underlying mechanism of personal control restoration. Notably, the benefits of restored personal control over one's environment do not generalize to anger (Experiments 2 and 3), because anger is associated with a sense that other people (rather than situational forces) are likely to cause negative outcomes, and these appraisals are not ameliorated by restoring personal control over one's environment.     

History of Religious Delusions and Psychosocial Functioning Among Mexican Patients with Paranoid Schizophrenia

The association between global functionality and religiosity among patients from developing and predominantly Catholic countries warrants attention. To compare religiosity and psychosocial functioning in Mexican schizophrenia patients with and without a history of religious delusions, seventy-four patients with paranoid schizophrenia were recruited. Patients with a history of religious delusions had more psychiatric hospitalizations and poorer psychosocial functioning compared with those without a history of religious delusions. No differences emerged between groups in the total scores of religiosity scales. A history of religious delusions rather than religiosity itself may have an influence on psychosocial functioning among Mexican patients with schizophrenia.

Holistic reasoning on the other side of the world: validation of the analysis-holism scale in Mexicans

The universality of cognitive processes has been called into question. Research suggests that individuals from Eastern cultures (e.g., China, Korea) when compared to individuals from Western cultures (e.g., the United States) prefer to reason holistically. This line of research has not been extended to cultural groups far removed from cultures traditionally surveyed in cross-cultural research such as Hispanics. We conducted two studies to understand: 1) the generalizability of the construct of holistic reasoning in Mexicans, and 2) the preferred reasoning style of Mexicans when compared to U.S. Americans. Results support the generalization of the factor structure of holistic reasoning as originally hypothesized by Choi, Koo, and Choi (2007). The results of Study 2 suggest that Mexicans scored higher than U.S. Americans on certain aspects of holistic reasoning.
