Tactile perception and the right hemisphere: a masculine superiority for imagery coding
Brain and Cognition
|July 1, 1983
Summary
This study explored hemispheric lateralization and tactile perception. Males showed a distinct advantage in using right-hemisphere imagery strategies for processing information.
Area of Science:
- Neuroscience
- Cognitive Psychology
Background:
- Hemispheric lateralization research indicates complex interplay between asymmetries, coding strategies, and sex differences.
- Understanding how individuals access and utilize information codes is crucial for cognitive studies.
Purpose of the Study:
- To investigate the relationship between instructed coding strategies (verbal vs. imagery) and tactile asymmetries.
- To examine sex differences in the utilization of hemispheric strategies during tactile perception.
Main Methods:
- Participants were instructed to use either a verbal (left hemisphere) or imagery (right hemisphere) strategy before tactile perception of ambiguous figures.
- A control group without specific strategy instructions was included for comparison.
Main Results:
- A significant overall relationship was found between instructed strategy and tactile asymmetries.
- This relationship was primarily driven by males demonstrating privileged access to right-hemisphere imagery codes.
Conclusions:
- Instructed coding strategies significantly influence tactile asymmetries.
- Males exhibit a notable advantage in employing right-hemisphere-dominant imagery strategies for tactile information processing.

01:33Somatosensation
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
01:14Motor and Sensory Areas of the Cortex
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.

01:11Sensory Perception: Organization of the Somatosensory System
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the stimulus...

01:05Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
01:23Somatosensory, Motor, and Association Cortex
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at the...
01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
