Extensive research has highlighted the importance of Need for Cognition (NFC) in various contexts, but our understanding of its development remains limited. In particular, the current psychological literature is relatively silent regarding the factors influencing NFC development. We aim to address this gap by proposing a developmental model of NFC based on the principles of the Cognitive Adaptation Trait Theory (CATT).

When students with high cognitive abilities disengage from school, this implies a severe loss of talent to students themselves and to society. Hence, it is important to understand how teachers can prevent disengagement and underachievement in high-ability students. Whereas a large body of research has demonstrated that need-supportive teaching (i.

  • The text outlines the objective of updating the 'Post-acute Level Of Consciousness scale' (PALOC-s) to reflect current scientific knowledge about consciousness levels.
  • Developed 20 years ago, the original scale helps track the progress of unconscious young patients during rehab, but advances in understanding necessitate changes in terminology and structure.
  • The revised scale, now called PALOC-sr, is ready for clinical use and should be validated for effective application in future research.

Whereas it has sometimes been asserted that the intellectually gifted would be more prone to develop mental health problems, empirical studies generally do not seem to support such claims. However, much of the available research has relied on preselected samples, introducing risks for sample selection bias. This study scrutinized the relationship between intellectual giftedness (defined as high cognitive ability) and mental health in a large, non-selective sample of early adolescents ( = 3409; 49.

Whereas both the family and school environment have been suggested to affect school burnout risks, the role of conditionally regarding parenting or teaching, in which affection is granted conditional on student achievement, in the development of school burnout has not yet been examined. This longitudinal study investigated students' academic contingent self-esteem and parental and teacher conditional regard as antecedents of school burnout. The study sample consisted of Flemish early adolescents (n = 3409; M = 12.

Article Synopsis
  • Deep brain stimulation (DBS) of the central thalamus is being researched as a way to improve consciousness in patients with severe brain injuries, showing varying degrees of success, yet the exact mechanism remains unclear.
  • A study using magnetoencephalography revealed that lower frequency DBS (50 Hz) led to a more significant increase in brain connectivity and neural activity compared to higher frequency settings, which also resulted in improvements in patient functions like visual pursuit and swallowing after years of inactivity.
  • Despite these enhancements, the patient's neural activity remained substantially lower than that of healthy individuals, indicating that while DBS can help re-activate certain brain functions, it doesn't fully restore cognitive capabilities in severely injured patients.

Background: The aim of this Delphi study was to reach consensus about definition, operationalization and assessment of visual pursuit (VP) and visual fixation (VF).

Methods: In a three-round international Delphi study, clinical and research experts on disorders of consciousness indicated their level of agreement on 87 statements using a 5-point Likert scale. Consensus for agreement was defined by a median of 5, an interquartile range (IQR) ≤ 1, and ≥ 80% indicating moderate or strong agreement.

School engagement and disengagement are important predictors of school success that are grounded in the social context of the classroom. This study used multilevel analysis to examine the contributions of the descriptive norms of friends, popular students and classmates regarding engagement and disengagement to the development of Students' own behavioral and emotional engagement and disengagement among Flemish 7th-graders ( = 3,409). Moderating effects of Students' self-esteem and cognitive ability were examined.

Introduction: The Pathways to Underachievement model (PUM; Snyder & Linnenbrink-Garcia, 2013) is a person-oriented framework identifying two distinct patterns of self- and value beliefs that help explain underachievement among cognitively highly able students. This framework was developed to clear up inconclusive findings from variable-centered underachievement research, but has not been previously empirically tested.

Methods: The present study aimed to test the PUM by investigating (a) whether the predicted motivational profiles are evident among a sample of high-ability students (IQ ≥ 120) beginning secondary school in Flanders, Belgium (N = 403, M = 12.

Peer relationships form a key developmental context. The current study investigated differences in peer acceptance between high-ability and average-ability youth, from the perspectives of teachers, peers, and students. Relying on the person-group similarity model, we also tested whether high-ability students' acceptance would depend on the peer group's mean ability level.

Article Synopsis
  • The vegetative state, also known as unresponsive wakefulness syndrome, presents significant challenges for rehabilitation specialists, particularly regarding the potential for recovery of consciousness.
  • Emerging research indicates that the traditional recovery timelines (3-6 months for non-traumatic, 12 months for traumatic brain injuries) may be too restrictive, though data on recovery odds remains limited.
  • Analysis of four cases revealed that signs of consciousness appeared much earlier than expected (5 weeks-2 months post-injury), but misinterpretation and diagnostic delays led to a lack of timely recognition, which affects both patient care and prognostic assessments.
