Learning strategy differentially impacts memory connections in children and adults

Even once children can accurately remember their experiences, they nevertheless struggle to use those memories in flexible new ways—as in when drawing inferences. However, it remains an open question as to whether the developmental differences observed during both memory formation and inference itself represent a fundamental limitation on children's learning mechanisms, or rather their deployment of suboptimal strategy. Here, 7–9-year-old children (N = 154) and young adults (N = 130) first formed strong memories for initial (AB) associations and then engaged in one of three learning strategies as they viewed overlapping (BC) pairs. We found that being told to integrate—combine ABC during learning—both significantly improved children's ability to explicitly relate the indirectly associated A and C items during inference and protected the underlying pair memories from forgetting. However, this finding contrasted with implicit evidence for memory-to-memory connections: Adults and children both formed A-C links prior to any knowledge of an inference test—yet for children, such links were most apparent when they were told to simply encode BC, not integrate. Moreover, the accessibility of such implicit links differed between children and adults, with adults using them to make explicit inferences but children only doing so for well-established direct AB pairs. These results suggest that while a lack of integration strategy may explain a large share of the developmental differences in explicit inference, children and adults nevertheless differ in both the circumstances under which they connect interrelated memories and their ability to later leverage those links to inform flexible behaviours.

Research Highlights

• Children and adults view AB and BC pairs related through a shared item, B. This provides an opportunity for learners to connect A–C in memory.
• Being encouraged to integrate ABC during learning boosted performance on an explicit test of A–C connections (children and adults) and protected from forgetting (children).
• Children and adults differed in when implicit A–C connections were formed—occurring primarily when told to separately encode BC (children) versus integrate (adults), respectively.
• Adults used implicit A–C connections to facilitate explicit judgments, while children did not. Our results suggest developmental differences in the learning conditions promoting memory-to-memory connections.

     

The influence of thinking dispositions on integration and recall of multiple texts

We investigated the association between thinking dispositions and two outcomes of multiple-texts comprehension: integration of conflicting information in argumentative essays; and recall of inferential information as an index of deep comprehension. We focused on two thinking dispositions, need for cognition (NFC) and actively open-minded thinking (AOT), as relevant individual differences in the processes involved in multiple-texts comprehension. NFC is the tendency to engage in and enjoy cognitively demanding activities, whereas AOT is the tendency to rationally evaluate arguments and supporting evidence, without being influenced by biases from one's own prior beliefs and prior knowledge. 73 university students completed perceived topic knowledge, perceived exposure to argumentative writing, and perceived competence in argumentative writing, NFC and AOT questionnaires, read two contradictory texts, wrote an argumentative essay, and recalled the information read 1 month later. Argumentative essays were assessed by length and level of integration of conflicting perspective. Text recalls were assessed by number of valid inferences included. Research questions were investigated through a path analysis model. The path analysis model had a good fit. NFC was indirectly associated with argumentation quality of the essay via the essay length. AOT was directly associated with the inferences included in the recall task. The present study contributes to the literature on multiple-texts comprehension by emphasizing the role of thinking dispositions.     

Unconscious integration: Current evidence for integrative processing under subliminal conditions

Integrative processing is traditionally believed to be dependent on consciousness. While earlier studies within the last decade reported many types of integration under subliminal conditions (i.e. without perceptual awareness), these findings are widely challenged recently. This review evaluates the current evidence for 10 types of subliminal integration that are widely studied: arithmetic processing, object-context integration, multi-word processing, same-different processing, multisensory integration and 5 different types of associative learning. Potential methodological issues concerning awareness measures are also taken into account. It is concluded that while there is currently no reliable evidence for subliminal integration, this does not necessarily refute ‘unconscious’ integration defined through non-subliminal (e.g. implicit) approaches.     

Atypical crossmodal emotional integration in patients with gliomas

The relevance of emotional perception in interpersonal relationships and social cognition has been well documented. Although brain diseases might impair emotional processing, studies concerning emotional recognition in patients with brain tumours are relatively rare. The aim of this study was to explore emotional recognition in patients with gliomas in three conditions (visual, auditory and crossmodal) and to analyse how tumour-related variables (notably, tumour localisation) and patient-related variables influence emotion recognition. Twenty six patients with gliomas and 26 matched healthy controls were instructed to identify 5 basic emotions and a neutral expression, which were displayed through visual, auditory and crossmodal stimuli. Relative to the controls, recognition was weakly impaired in the patient group under both visual and auditory conditions, but the performances were comparable in the crossmodal condition. Additional analyses using the ‘race model’ suggest differences in multisensory emotional integration abilities across the groups, which were potentially correlated with the executive disorders observed in the patients. These observations support the view of compensatory mechanisms in the case of gliomas that might preserve the quality of life and help maintain the normal social and professional lives often observed in these patients.     

Towards a synthesis of personality,temperament, motivation,emotion and mental health models within the Circumplex of Personality Metatraits

The paper presents empirical verification of the Circumplex of Personality Metatraits (CPM) that overcomes some problems with the Big Five and enables the integration of various constructs and models developed within many sub-disciplines of psychology. Empirical verification of the model was conducted on a group of 1045 participants in two steps: (1) validation of the model (e.g., the circular arrangement of the metatraits, and relations with the Big Five); (2) verification of the synthesizing potential of this model by testing the predicted locations of temperamental traits, interpersonal traits, values, affects, and mental health constructs within the CPM. It has been found that the CPM can be treated as a matrix accommodating constructs described by circumplex, circular, and noncircular models.     

Using Relational-Cultural Theory to Conceptualize International Student Transitions

ABSTRACT

In this article, Relational-Cultural Theory (RCT) is applied to international student transition experiences. The purpose of this phenomenological study was to describe the lived experiences of international students transitioning to college life in the rural United States using the principles of RCT. Five women and four men enrolled at a mid-sized university agreed to participate in the study. In the data analysis phase, four components of RCT emerged as themes. The authors provide implications for campus-based mental health professionals (e.g., college counselors).     

Fitting in: How the intergroup context shapes minority acculturation and achievement

ABSTRACT

Children of immigrants are at risk of underachieving in school with long-lasting consequences for future life-chances. Our research contextualises the achievement gap by examining minority acculturation experiences in daily intergroup contact across different intergroup contexts. Acculturation researchers often find an adaptive advantage for minority youth with an integration-orientation (combining both cultures). But findings from Europe are inconclusive. Looking beyond individual differences in acculturation-orientations, this review shifts focus to the intergroup context of minority acculturation and achievement. We discuss longitudinal, multi-group, multi-level and experimental evidence of the up- and downsides of integration for minority inclusion and success in European societies. Our studies show that both (1) intergroup contact experiences and (2) intergroup ideologies affect achievement – either directly or through the interplay of (3) acculturation-norms, defined as shared views on acculturation in social groups, with individual acculturation-orientations. The findings suggest how schools can reduce achievement gaps through improving intergroup relations.     

Concurrent intramodal learning enhances multisensory responses of symmetric crossmodal learning in robotic audio-visual tracking

Tracking an audio-visual target involves integrating spatial cues about target position from both modalities. Such sensory cue integration is a developmental process in the brain involving learning, with neuroplasticity as its underlying mechanism. We present a Hebbian learning-based adaptive neural circuit for multi-modal cue integration. The circuit temporally correlates stimulus cues within each modality via intramodal learning as well as symmetrically across modalities via crossmodal learning to independently update modality-specific neural weights on a sample-by-sample basis. It is realised as a robotic agent that must orient towards a moving audio-visual target. It continuously learns the best possible weights required for a weighted combination of auditory and visual spatial target directional cues that is directly mapped to robot wheel velocities to elicit an orientation response. Visual directional cues are noise-free and continuous but arising from a relatively narrow receptive field while auditory directional cues are noisy and intermittent but arising from a relatively wider receptive field. Comparative trials in simulation demonstrate that concurrent intramodal learning improves both the overall accuracy and precision of the orientation responses of symmetric crossmodal learning. We also demonstrate that symmetric crossmodal learning improves multisensory responses as compared to asymmetric crossmodal learning. The neural circuit also exhibits multisensory effects such as sub-additivity, additivity and super-additivity.
