Learn: Developmental Psychology: Intelligence, Memory, and the Flynn Effect

What is the Flynn effect?

The Flynn effect refers to the observed rise in IQ scores over time, suggesting that intelligence may be influenced by environmental factors.

What are the two types of intelligence discussed in the lecture?

Crystallized intelligence and fluid intelligence.

Define crystallized intelligence.

Crystallized intelligence is the accumulation of knowledge, facts, and skills that are acquired through education and experience.

Define fluid intelligence.

Fluid intelligence is the capacity to think logically and solve problems in novel situations, independent of acquired knowledge.

How does crystallized intelligence change with age?

Crystallized intelligence remains stable and can continue to grow well into the 70s.

How does fluid intelligence change with age?

Fluid intelligence tends to decline earlier, often noticeable in cognitive abilities as early as the 30s.

What is the relationship between crystallized and fluid intelligence as we age?

As fluid intelligence declines, crystallized intelligence can compensate for those deficits.

What factors can influence individual differences in intelligence?

Engagement in physical activity and the use of higher-order critical thinking skills.

Memory is the ability to retain information, store it, and retrieve it on demand.

What does the information processing perspective compare memory to?

It likens memory to a computer, involving input, output, storing, and accessing information.

What is sensory memory?

Sensory memory is the initial step in processing information picked up through our senses.

What senses are involved in sensory memory?

Senses include hearing, taste, sight, smell, and touch.

What happens to irrelevant information in sensory memory?

The brain filters out irrelevant information to determine what is important to store.

How long does information typically stay in short-term memory?

Information can be held in short-term memory for seconds to a few minutes.

What determines if information moves from short-term to long-term memory?

The importance of the information evaluated during short-term memory storage.

How can emotionally charged experiences affect memory?

Emotionally charged experiences can be easily coded into long-term memory.

What is the role of cultural pressures in multitasking?

Cultural pressures can distract individuals and affect their ability to focus on important tasks.

What is the impact of writing by hand on memory retention?

Writing by hand can enhance the ability to retain new information compared to using technology.

What is the difference in sensory processing between younger and older adults?

Older adults may struggle to filter out sensory input, leading to distractions.

What is the significance of critical thinking in higher education?

Critical thinking is essential for cognitive development and is encouraged in college settings.

What is the effect of multitasking on social interactions?

Multitasking can detract from the quality of social interactions and engagement.

How does physical exercise relate to problem-solving?

Physical exercise can lead to creative ideas and solutions during activities like walking.

What is the process of filtering information in sensory memory?

The brain constantly scans sensory input to decide what is relevant and what to discard.

What are the implications of multitasking in educational settings?

Multitasking may hinder students' ability to engage fully with learning material.

What is the importance of group work in learning?

Group work encourages collaboration and deeper understanding of material.

How does emotional experience influence memory coding?

Traumatic or highly positive experiences can be coded into long-term memory automatically.

What is the role of attention in memory processing?

Attention is crucial for determining which information is stored in memory.

What is the relationship between education and cognitive health?

Higher education is linked to better cognitive health and intelligence over time.

How does the environment affect sensory memory?

Environmental factors like temperature and noise can influence sensory processing.

What is the importance of engaging with material in a non-digital format?

Engaging with material through writing can improve retention and memory quality.

What are some factors contributing to the Flynn Effect?

Increased emphasis on education, a more nutrient-rich diet, better standardized testing performance, and cognitive stimulation.
