Motivation Bindra applied research in pharmacology and neurology to human executive functioning. He defined motivation as a dynamic interaction between biological, social, internal, and external factors. Internal factors included physiological and driving cues, and external factors included environmental stimuli. Bindra strongly felt that motivation, as a topic in psychology, could unify diverse psychological subfields that typically held conflicting ideas. Bindra was a forerunner in integrating methods and findings from both sides of the
nature versus nurture debate to support his research in motivation. His research combined a diverse set of theories and topics, including goal direction, sensory cues, arousal, blood chemistry, and reinforcement. This work culminated in the publication of his first book in 1959,
Motivation: A Systematic Reinterpretation, which attempted to systematize the contemporary motivation literature within a new framework. Based on evidence from human experimental data and animal paradigms, the book explored the underlying explanations for goal-directed motivation in humans.
Methods in neuropsychology In the late 1950s, Bindra developed novel pharmacological and neuropsychological experimental techniques for use in rats. For example, one of his experiments examined the differing effects methylphenidate, chlorpromazine, and
imipramine had on freezing and immobility in rats. Bindra found that these drugs decreased and altered the pattern of this response in rats, indicating a type of induced avoidance behaviour.
Other aspects of research In his second book, 'A Theory of Intelligent Behaviour' (1976), Bindra defined intelligence as a set of adaptive, directed, anticipative, and creative behaviours intended to bring about desired outcomes. This book highlighted the many neural connections enabling cognitive knowledge, motivational arousal, and sensory motor coordination. Bindra argued that together, their interactions produced intelligence. In a similar vein, Bindra had radical ideas regarding human learning: he rejected the typical
operant conditioning theory of response-reinforcement. Instead, he argued that learning was produced by our cognitive representations of our external environments; these schemas could be influenced by context, incentive, and motivation. Towards the end of his career, Bindra expanded his research to include psychological disorders manifesting in behavioural problems. He published papers about human weeping and language in apes in 1972 and 1981, respectively. ==Honours and awards==
