Recognition and Recall-Like Processes in the Long-Term Reconstruction of Order

Abstract

Four experiments examined whether the recovery of an item's position in a sequence taps processes similar to recognition and/or recall. Across the experiments, subjects either recalled, recognised, or made position judgements about list items that differed in word frequency. Typical word frequency effects were found in recall and recognition, but frequency failed to affect measures of position memory consistently across the four experiments. Despite the apparent procedural similarities across tasks, it appears that the recovery of position information may tap mnemonic processes that are different from those tapped by recognition and recall. Implications of these findings for current models of position memory are discussed.     

Executive Resources and Item-Context Binding: Exploring the Influence of Concurrent Inhibition,Updating, and Shifting Tasks on Context Memory

Previous research has demonstrated that context memory performance decreases as a result of cognitive load. However, the role of specific executive resources availability has not been specified yet. In a dual-task experiment, participants performed three kinds of concurrent task engaging: inhibition, updating, or shifting operations. In comparison with a no-load single-task condition, a significant decrease in item and context memory was observed, regardless of the kind of executive task. When executive load conditions were compared with non-specific cognitive load conditions, a significant interference effect was observed in the case of the inhibition task. The inhibition process appears to be an aspect of executive control, which relies on the same resource as item-context binding does, especially when binding refers to associations retrieved from long-term memory.     

Good and bad effects of phonological similarity on word and nonword recall: The role of beginnings and ends

This study explored whether earlier results of differential (harmful vs. helpful) short-term memory effects of shared syllables at nonword beginnings compared to ends could be replicated for lists of bisyllabic real words. We studied immediate serial recall of lists that had phonologically redundant syllables at the beginnings or ends of two-syllable words or nonwords. The results showed that redundancy at the beginning had a negative effect on both types of material. Redundancy at the end did not impair memory for nonwords but harmed the serial recall of words. Irrespective of lexicality, lists of beginning-redundant items were more difficult to recall than end-redundant items. The distribution of errors suggested that the better recall of end-redundant lists compared to beginning-redundant lists was related to a positive effect at encoding and/or retention, independent of effects at recall, for both words and nonwords.     

Identifying faking bad on the Minnesota Multiphasic Personality Inventory-Adolescent with Mexican adolescents

This study examined the extent to which the validity scales of the Minnesota Multiphasic Personality Inventory-Adolescent identified Mexican adolescents who were instructed to fake bad. Validity scales data were used to differentiate between nonclinical adolescents instructed to fake bad and both clinical and nonclinical adolescents who received standard instructions. Participants were 59 male and 87 female Mexican high school students and 59 male and 87 female Mexican adolescents from clinical settings. This is the first study onfaking with adolescents in Mexico. The F, Fl, and F2 Scales and the F-K index discriminated adequately between the three different groups. Results were similar to those previously reportedfor adults and adolescents in Mexico and the United States. High positive and negative predictive powers and overall hit rates were obtained in this study. Higher cut scores were needed to discriminate between the groups of girls than between the groups of boys.     

Extending the theory of realistic conflict to competition in institutional settings: intergroup status and outcome

The authors analyzed the extent to which the Theory of Realistic Conflict can be extended to institutional settings in which groups are not actively involved in decisions but are passive targets of decisions taken by an institutional authority (the rector). A negative interdependence between the in-group (psychology) and a high- or low-status outgroup (engineering versus nursing) was established by an institutional authority (the rector). The competition (induced by the rector) was beneficial (an increase in the budget previously invested in the faculty) or detrimental (a decrease in the budget) for the in-group. The results confirmed that competition affects mutual attitudes, images, and behaviors of groups even if the groups are passive targets of decisions that the institutional authority makes. Moreover, competition--regardless of whether beneficial or detrimental--deteriorated images of and attitudes toward high-status out-groups. In contrast, competition improved images and opinions about low-status out-groups, but only in the loss condition.     

Reduced Alternating Gaze During Social Interaction in Infancy is Associated with Elevated Symptoms of Autism in Toddlerhood

In typical development, infants often alternate their gaze between their interaction partners and interesting stimuli, increasing the probability of joint attention toward surrounding objects and creating opportunities for communication and learning. Children with Autism Spectrum Disorder (ASD) have been found to engage less in behaviors that can initiate joint attention compared to typically developing children, but the role of such atypicalities in the development of ASD during infancy is not fully understood. Here, using eye tracking technology in a live setting, we show that 10-month-olds at high familial risk for ASD engage less in alternating gaze during interaction with an adult compared to low risk infants. These differences could not be explained by low general social preference or slow visual disengagement, as the groups performed similarly in these respects. We also found that less alternating gaze at 10 months was associated with more social ASD symptoms and less showing and pointing at 18 months. These relations were similar in both the high risk and the low risk groups, and remained when controlling for general social preference and disengagement latencies. This study shows that atypicalities in alternating gaze in infants at high risk for ASD emerge already during the first 10 months of life - a finding with theoretical as well as potential practical implications.     

Assessing False-Belief Understanding in Children with Autism Using a Computer Application: A Pilot Study

We have developed a False-Belief (FB) understanding task for use on a computer tablet, trying to assess FB understanding in a less social way. It is based on classical FB protocols, and additionally includes a manipulation of language in an attempt to explore the facilitating effect of linguistic support during FB processing. Specifically, the FB task was presented in three auditory conditions: narrative, silent, and interference. The task was assumed to shed new light on the FB difficulties often observed in Autism Spectrum Disorder (ASD). Sixty-eight children with ASD (M?=?7.5 years) and an age matched comparison group with 98 typically developing (TD) children were assessed with the FB task. The children with ASD did not perform above chance level in any condition, and significant differences in success rates were found between the groups in two conditions (silent and narrative), with TD children performing better. We discuss implications, limitations, and further developments.     

African American and Mexican American Youths’ College Adjustment and Perceptions of Parental Academic Socialization: Interactions Between Ethnicity and Parental Education

In a sample of 283 African American and Mexican American college students, we investigated the effects of ethnicity and parental education on three dimensions of parental academic socialization (PAS), active involvement, autonomy support, and demanding hard work, and their impact on college adjustment. Controlling for parental education, African Americans reported higher parental active involvement. Academic self-efficacy mediated the effects of both demanding hard work and autonomy support on college adjustment, controlling for parental education. Moderated mediation models suggested that effects of both demanding hard work and autonomy support on academic self-efficacy were stronger for African Americans than for Mexican Americans.
