lateralisation

Question 1

Lateralization

Answer 1

Lateralization refers to the division of cognitive functions between the left and right hemispheres of the brain.

Question 2

Historical Context of lateralisation

Answer 2

Broca’s and Wernicke’s areas highlighted the localization of language functions in the left hemisphere.

Question 3

Evidence Supporting Lateralization

Answer 3

language Processing/ Spatial Abilities/ Motor Control

Question 4

Evidence Supporting Lateralization: Language Processing

Answer 4

Left hemisphere dominance in language processing is supported by lesion studies, fMRI, and split-brain patient research (Gazzaniga et al., 2019).

Question 5

Evidence Supporting Lateralization: Spatial Abilities

Answer 5

The right hemisphere is associated with spatial abilities and visuospatial processing (Gazzaniga et al., 2019).

Question 6

Evidence Supporting Lateralization: Motor Control

Answer 6

Left hemisphere controls movements on the right side of the body, and vice versa (Smith & Kosslyn, 2007).

Question 7

Critical Evaluation of Research of lateralisation

Answer 7

Methodological Considerations/ Functional Overlap/ Cultural and Linguistic Factors

Question 8

Future Directions of Research of lateralisation

Answer 8

Clinical Practice/ Nuanced Approaches/ Advanced Techniques

Question 9

Wernicke-Geschwind model of language

Answer 9

neurological model that attempts to explain the neural mechanisms underlying language comprehension and production

Question 10

Limitations and Criticisms of Wernicke-Geschwind model of language

Answer 10

inadequate to Explain All Language Disorders/ failure to Address Hemispheric Variability/ newer methods challenge the simplistic view of the Wernicke-Geschwind model- such as fMRI

Question 11

Describe the left hemisphere’s role in-related tasks.

Answer 11

The left hemisphere is pivotal in language-related tasks, as demonstrated by lesion studies, neuroimaging techniques such as fMRI, and split-brain patient research.

Question 12

How could advanced neuroimaging techniques and longitudinal studies contribute to understanding brain lateralization?

Answer 12

Advanced neuroimaging techniques and longitudinal studies could provide a more comprehensive understanding of the dynamic nature of lateralization.

Question 13

the phenomenon of lateralization of function in the human brain

Answer 13

Lateralization of function in the human brain refers to the specialization of certain functions in either the left or right hemisphere, particularly evident in language processing, spatial abilities, and motor control

Question 14

Describe the factors that future research on brain lateralization should consider.

Answer 14

Future research on brainization should consider individual differences, task complexity, environmental factors for a more nuanced understanding.

Question 15

What are the implications of understanding the lateralization of function?

Answer 15

Understanding the lateralization of function has significant implications for clinical practice, education, and cognitive rehabilitation, impacting how these areas are approached and managed

Question 16

How does critical evaluation of research methodologies contribute to understanding lateralization?

Answer 16

Critical evaluation of research methodologies and potential biases is essential to avoid oversimplification, neglect of interindividual variability, and to consider functional overlap, compensatory mechanisms, and the influence of cultural and linguistic factors on lateralization.

Question 17

Define Broca’s and Wernicke’s areas and their significance in the context of lateralization of function.

Answer 17

Broca’s area is crucial for language production, while Wernicke’s area is important for language comprehension. Their localization in the left hemisphere highlights the lateralization of language functions.

Question 18

How does the evidence support the dominance of the left hemisphere in language processing?

Answer 18

Substantial evidence supports the left hemisphere’s dominance in language processing, particularly through the localization of Broca’s and Wernicke’s areas for language production and comprehension.

Question 19

Describe the historical significance of Broca’s and Wernicke’s areas in understanding lateralization of function.

Answer 19

The discovery of Broca’s and Wernicke’s areas, crucial for language production and comprehension, respectively, highlighted the idea that specific functions could be localized in distinct brain regions, contributing to the understanding of lateralization of function.

Question 20

What does the term ‘lateralization’ refer to in the context of the human brain?

Answer 20

The term ‘lateralization’ refers to the division of cognitive functions between the left and right hemispheres of the human brain, highlighting the specialization of functions in distinct brain regions.

Question 21

Who was Paul Broca?

Answer 21

Conducted a post mortem study of aphasic patients/ Patients had a subtype of aphasia characterized by inability to produce language

Question 22

What did Broca’s postmortem discoveries reveal?

Answer 22

Aphasic patients had damage to the left inferior prefrontal cortex

Question 23

Where is there greater activation on language tests?

Answer 23

left hemisphere
