7. Your ability to perceive the sound of a trumpet amongst a cacophony of sounds in a jazz ensemble is because of what type of learning? (the answer is not d)  

a) instrumental learning

b) perceptual learning

c) habituation

d) procedural learning

Explanation / Answer

2. B; It alerts us of potential benefits and threats.

Salience or saliency is the quality of an object, thing, person or any visual observable thing which stands out in relation to its neighbour, Detection of salience is considered to be a key attention mechanism that facilitates learning and survival by enabling organisms to focus their limited non cognitive and cognitive resources on the most relevant subset of the available sensory data.

3. C; Salient search

The green heart stands out in the field of green triangles and red heart. Salience or saliency is the quality of an object, thing, person or any visual observable thing which stands out in relation to its neighbour.

6. C; to control for exercise causing weight loss

Yoked control design is a research design where matched research subjects are joined together recieving the same stimulus. In this experiment the disc rotates when ever one rat falls asleep but does not rotate when one is awake and the yoked control when improvising when the disc is stationary. hence the yoked control here is used as a control fow weight loss caused by exercise.

7. B; perceptual learning  

  Perceptual learning is learning better recognition skills. Such as differentiating two musical tones from one another or categorizations of spatial and temporal signal sequence patterns relevant to real- world skill.
