The effect of ecstasy/polydrug use on prospective memory and executive processes
… to examine the range of prospective memory and executive function deficits in ecstasy/polydrug users and the role of these processes in accounting for the observed prospective memory performance deficits. Using a variety of laboratory and self-report measures of prospective memory and a …

The role of long- and short-term typical dose, concurrent alcohol consumption and executive processes in ecstasy related prospective memory deficits.
… deficits. Chapter 10 investigated the role of executive functioning processes in accounting PM deficits in ecstasy users. Verbal word fluency, updating, shifting and inhibition executive functions did not predict PM performance in ecstasy users. Chapter 11 used correlational analyses to …

The relationship of self-regulation and academic achievement in college students with and without attention-deficit/hyperactivity disorder: a brain-behavior perspective
… among three constructs: (a) the underlying executive processes of self-regulation, (b) self-regulation behaviors, and (c) academic achievement in college students with and without ADHD.

Falling Head Over Heels: Investigating the higher-level cognitive and electrophysiological processes underlying gait control and falls in older adults and stroke survivors
… become increasingly apparent, with higher-level executive functions exhibiting a clear relationship with falls and cognitive decline with ageing (Morris, Lord, Bunce, Burn, & Rochester, 2016). This research aims to address a gap in the literature by identifying the specific higher-level executive …

Working Memory Deficits in Children: Contributions of Executive Control Processes and Symptoms of ADHD
… (c) the episodic buffer, and (d) the central executive (Baddeley and Hitch, 1974; Baddeley, 2003). The central executive has been fractionated into four subprocesses: (a) sustained attention, (b) selective attention/inhibition (c) shifting attention, and (d) control of retrieval from long-term …

Neuropsychological Deficits in Adolescents with Psychopathic Characteristics: Callous and Unemotional Symptoms
… with psychopathic characteristics, looking at executive functions and how they differ in individuals who score high on callous/unemotional traits (CU; Cleckley, 1941; Frick et al., 1994; Hare, 1991, 1993). Then apply these findings to the cognitive models. Literature has not examined the …

Episodic Memory during Middle Childhood: Active vs. Passive Processing
… more low resolution images than clear images. Executive function ability was also assessed to investigate possible contributions to performance. Furthermore, this study investigated whether frontal and temporal brain electrophysiology predicted unique variance in recall performance. Results …

Environmental Context in Child Behavioural Difficulties: Exploring the role of Executive Function (EF) and Emotion Regulation (ER)
Executive Function (EF) deficits are evidenced in children with behavioural difficulties. Yet, it is not clear how specific executive processes impact maladaptive behaviour in this population. What is more, previous research suggests that not only are EF and emotion regulation (ER) intrinsically …

Salience and Frontoparietal Network Patterns in Children with Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder
… similar and both exhibit atypical attention and executive functioning. Mischaracterizations between these two disorders can lead to inappropriate medication regimes, significant delays in special services, and personal distress to families and caregivers. There is evidence that ASD and ADHD are …

Challenging frontal lobe capacity using lateralized vestibular stress: A functional cerebral systems approach to a clinical risk for falls
… that linked the vestibular modality with executive domains by means of a functional cerebral systems framework. The claim was that frontal regions exert regulatory control over posterior systems for sensation and autonomic functions in a dense, interconnected network with right hemisphere …

Affective Modulation of Executive Control
… and place heightened demands on control. Yet the executive control mechanisms that subsequently resolve that interference have not been well characterized. Although many failures of executive control have emotion at their core, numerous questions remain in the field regarding interactions between …

Attentional and affective mechanisms in worry and rumination
… Lastly, we investigated which attentional and executive processes, if any, are involved in the initiation and termination of worry and rumination, while considering the potential influence of negative temperament. We found that the structural relationship between worry and rumination is best …

Investigating the neurobiology regulating cognitive effort allocation using a rodent model of cost/benefit decision making
… humans is the cost of cognitive effort, in which executive processes spanning attention, working memory, reasoning, and the like are taxed. This form of effort is in contrast to the physical effort costs that have generally been the focus of the cost/benefit decision-making literature. This thesis …

Relationship and collective impact of attention, processing speed, and working memory: Validation of the cognitive facilitation/inhibition domain of the Integrated SNP/CHC model
… as supportive of higher-order cognitive processes; however, the relationship between attention, PS, and WM is rarely investigated (Fry & Hale). In recognition of the consistencies between these three constructs, a recent model of pediatric neuropsychological functioning proposes a …

Neuroimaging and behavioral investigation of declarative memory in South African children prenatally exposed to alcohol
… and indirectly (via bottom-up and top-down processes), a critical cognitive mechanism that supports successful declarative memory functioning (viz., memory encoding), in children with FASD. Data were collected from a sample (N = 88) of South African children with and without PAE. In Study I, …

Errorless Learning of Prospective Memory Tasks: An Experimental Investigation in People with Memory Disorders.
… a combination of mnemonic, attentional and executive abilities. PM tasks can be particularly challenging for people with cognitive impairment, and it is important to identify effective means of rehabilitation. Errorless Learning (EL) is an encoding technique that results<br/>in superior …

Diagnosis of Cognitive Impairment using Multiple Data Modalities
… functions including memory, processing speed and executive processes, has been associated with ageing for sometime. It is understood that every human will go through this process, but some will go through it faster, and for some this process starts earlier. Differentiating between cognitive …

EXAMINING THE NEUROBIOLOGY OF NON-SUICIDAL SELF-INJURY IN CHILDREN AND ADOLESCENTS: THE ROLE OF REWARD RESPONSIVITY

The relationship between autobiographical memory an executive functions in older adults
… memory performance and its relationship with executive functioning in normal and pathological ageing. The particular focus was on two aspects of autobiographical memory - recall specificity and fluency - that have been little investigated in cognitive ageing research to date. The literature …

From working memory to maths: A multi-measure physiological investigation of the impact of anxiety
… measures to both anxious responses and executive processes make these measures appealing for advancing our understanding of maths anxiety (MA). The overarching research question asked whether anxiety affects the accuracy of the representations in WM, process that is thought to be central …
