What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul Jan 2020

What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul

Theses and Dissertations (Comprehensive)

Memory is undoubtedly one of the most important processes of human cognition. A long line of research suggests that recognition relies on the assessment of two explicit memory phenomena: familiarity and recollection. Researchers who support the Dual Process Signal Detection (DPSD) model of recognition memory link the FN400 component (a negative ERP deflection peaking around 400 ms at frontal electrodes) with familiarity; however, it is currently unclear whether the FN400 reflects familiarity or implicit memory. Three event-related potentials (ERP) studies were conducted to determine whether implicit memory plays a role in setting up encoding strategies, and how these encoding strategies …


Social Problems, Biomedical Answers? How Causes Of Social Problems Affect Choice Of Solutions, Bianca C. Dreyer Jan 2016

Social Problems, Biomedical Answers? How Causes Of Social Problems Affect Choice Of Solutions, Bianca C. Dreyer

Theses and Dissertations (Comprehensive)

With rapid advances in behavioural genetics, scientists are identifying an increasing array of genetic influences on human behaviour. Public misconceptions about the function of genes often lead to the oversimplification of the role of genes in behaviour (Dar-Nimrod & Heine, 2011). To date, no study has systematically investigated whether simply learning about genetic causes of behaviour affects people’s preferred solutions to problematic behaviours. The present research program includes three studies that were designed to examine the psychological effects of exposure to genetic etiology for problematic behaviour, in particular aggression, and investigated how this information influences endorsement of solutions, rating of …


The Tactile Motion Aftereffect, Peggy Joanne Planetta Jan 2009

The Tactile Motion Aftereffect, Peggy Joanne Planetta

Theses and Dissertations (Comprehensive)

The tactile motion aftereffect (tMAE) is a perceptual phenomenon in which illusory motion is reported following adaptation to a unidirectionally moving tactile stimulus. Unlike its visual counterpart, relatively little is known about the tMAE. For that reason, the purpose of this dissertation was to gain a better understanding of the tMAE using both psychophysical and neuroimaging techniques. In a series of five experiments the skin was adapted using a plastic cylinder with a square-wave patterned surface. Chapter 2 consists of two experiments, both of which adapted the glabrous surface of the right hand. Experiment 1 showed that the prevalence, duration, …


The Effects Of Expectancy, Task Importance And Self-Attention On Task Persistence, Jim Jewett Jan 1986

The Effects Of Expectancy, Task Importance And Self-Attention On Task Persistence, Jim Jewett

Theses and Dissertations (Comprehensive)

This study was designed to examine the relative power of control theory (Carver, 1979) and self-efficacy theory (Bandura, 1977) in predicting behavioral persistence. This study employed a 2 X 2 X 2 X 2 factorial design. One hundred and twelve undergraduate females were exposed to high and low levels of self-attention and task importance as well as positive and negative self-efficacy and outcome expectancies. Following failure on an anagram task subjects’ persistence in solving in insoluble design puzzle was assessed. Contrary to the hypotheses, the results suggested that self-efficacy expectancies, outcome expectancies, task importance and self-attention do not influence persistence …


The Modification Of Smoking Behaviour: A Research Evaluation Of Aversion Therapy, Hypnotherapy, And A Combined Technique, Herman Surkis Jan 1977

The Modification Of Smoking Behaviour: A Research Evaluation Of Aversion Therapy, Hypnotherapy, And A Combined Technique, Herman Surkis

Theses and Dissertations (Comprehensive)

This study compared aversion therapy, hypnotherapy, and a combined method. It was predicted that the treatment of imagined behaviour would generalize to overt behaviours. Individuals were randomly assigned to one of three groups: the aversion group with shock contingent on imagined behaviour, and finally the combined group which consisted of traditional hypnotherapy in combination with aversion therapy. The treatments were contained on separate cassettes with each subject receiving his appropriate cassette. Subjects met in groups of 3-5 individuals, twice a week for three weeks. Individuals acted as their own controls through the establishment of a pre-treatment baseline of smoking rate. …


An Assessment Of The Role Of Information Inherent In Positive And Aversive Social Reinforcement Employing A Finger Maze Task With Male And Female Subjects And Experimenters, Brian Westley Strutt Jan 1971

An Assessment Of The Role Of Information Inherent In Positive And Aversive Social Reinforcement Employing A Finger Maze Task With Male And Female Subjects And Experimenters, Brian Westley Strutt

Theses and Dissertations (Comprehensive)

Forty-eight male and 48 female grade 12 high school students were assigned in groups of 8 to a 2 (sex of S X 3 (treatment) X 2 (sex of E) factorial design experiment. Each S was presented with a finger maze task under one of three experimental treatments: censure-nothing with S being told “WRONG” for an incorrect response, nothing for a correct response; reward-nothing, with S being told “CORRECT” for a correct response, nothing for an incorrect response; nothing-nothing, with Ss being told nothing for either a correct or incorrect response. The task required that a binary decision be made …


Shock Intensity And Task Difficulty As Determiners Of Avoidance And Escape Learning In Rats, Arthur Louis Jan 1971

Shock Intensity And Task Difficulty As Determiners Of Avoidance And Escape Learning In Rats, Arthur Louis

Theses and Dissertations (Comprehensive)

Thirty-six naive female hooded rats were divided randomly into three groups and tested in an instrumental escape and avoidance learning situation involving three degrees of task difficulty. Each group was also randomly subdivided into four subgroups, each of which underwent a different shock intensity level. The purpose of this study was to test the Yorkes-Dodson law which states that (a) there is an optimal level of punishment intensity for any given task (or an inverted-U curve relating shock intensity and performance) and (b) this optimal intensity decreases as task difficulty increases. The results supported (a) but not (b).
