How is Dichotic Listening studied? - by asking people to wear earphones; one message is presented to the left ear, and a different message is presented to the right ear. Summarize Kosslyn's classic research on distances in mental images and scanning times. Summarize Paivio's research using mental clocks and the angles formed by the two clock hands. Do these findings support the analog position or the propositional position? - Kosslyn -seems like ppl use analog code for simple figures, and ...

Children who do not fit into Ainsworth's three original categories now are typically classified as: - disorganized secure avoidant resistant disorganized In Bowlby's attachment theory, the secure base refers to: - a special setting developed for needy, dependent infants a comfortable and safe home setting the evolutionary roots of how children become attached to caregivers the haven of safety a caretaker provides that allows a child to explore the environment the haven of safety...

Developmental Psychology - - the scientific study of physical, cognitive, and social change throughout the life span - is the scientific study of age-related changes in behaviours, thinking, emotion, and personality. Domains of Development - 1) Physical Domain: includes changes in the size, shape, and characteristics of the body. 2: Cognitive Domain: includes changes in thinking, memory, problem-solving, and other intellectual skills. 3) Social/Emotional Domain: involves variables that are...

Weapon-focus effect - the tendency for the presence of a weapon to draw attention and impair a witness's ability to identify the culprit Cross-race identification bias - the tendency for people to be more accurate at recognizing members of their own racial group than of other groups Misinformation effect - the tendency for false postevent misinformation to become integrated into people's memory of an event Polygraph - a mechanical instrument that records psychological arousal from mul...

Unit 1 - In what year was the term software engineering coined by a NATO study group? - 1967 Why is so much of today's software not considered to have been engineered? - What is the life cycle of software engineering? - A life-cycle model is a description of the steps that should be performed when building a software product. What is the relationship between computer science and software engineering? - Name some of the problems resulting from team programming. - Interfacing pr...

A data structure is - a particular way of organizing data in a computer so that it can be used efficiently An Abstract Data Type is - A set of objects together with a set of operations (They are a mathematical abstraction) Common Trade-offs - Time vs Space Making one operation faster may make another operation slower Providing more operations (making the data structure more general) may make some operations less efficient Operations are revealed through? - Interfaces and methods ...

What is software engineering? a discipline whose aim is the production of fault-free software, delivered on time and within budget, that satisfies the client's needs. The software must be easy to modify when the user's needs change What is classical software engineering life cycle model? 1. requirements 2. analysis/specification 3. design phase 4. implementation phase 5. post-delievery phase 6. retirement what is modern view of maintenance software undergoes modifications to code and...
