"are there other personality traits that have been identified in animals?" There are quite a bit of hits on Google about this. Here's a foundation dedicated to research on animal personalities: The Animal Personality Institute (API), founded in 2004, is an interdisciplinary group of researcher dedicated to advancing the scientific understanding of ...

As a slight modification of your statement: blood flow increases wherever activity in the brain increases. The type of fMRI that uses this principle is blood-oxygenation-level-dependent fMRI or BOLD fMRI. MRI in general detects signals by picking up proton signals from water molecules. This proton signal is basically caused by magnetizing the protons ...

It's not my area, but a quick Google revealed this one. The McGill Friendship Questionnaire - Respondent's affection (MFQ-RA). Item and validation information is available on the site. It also mentions that it takes inspiration from "the Friendship Questionnaire" and the "Friendship Qualities scale". So they might also be worth checking out.

Obtaining: Yes, the items are listed in Bukowski et al (1994). See Table 1. You could always email the author explaining your research project and ask him whether he would allow you to use the measure. Scoring: A quick look suggests that each item is scored on a 1 to 5 scale. Table 1 suggests that there is a scale-level, and subscale-level of scoring (i.e., ...

There a are globally two perspectives the discrete perspective uses a categorization system. There are many different systems, with more or less core emotions and sub-emotions. As the one shown in your post. the dimensional perspective considers one, mainly two, sometimes more, scales to identify an emotional value. Valence (happy/sad) and arousal ...

It is going to mean bad things. If you can only create stimuli with a predefined non uniformly sampled set of "levels" then the the corresponding percent correct that the staircase will track will depend on the threshold of an individual observer. For example, if you can create stimuli with levels of 0, 1, 2, 3, ..., 100, 110, 130, 170, 250, 410, where for ...

Just to give you a few ideas. The ideas are ordered from better to worse. They are also mostly ordered from serious and expensive research to less serious and cheap research. Randomised control trial: If you are really interested in causality, you would randomly allocate a large group of people to either and exercise or one or more control conditions ...

It's unclear if the idea of 'translation' from one personality framework to another is a meaningful concept. A score on any given personality factor represents some weighted combination of measures - usually endorsement of questionnaire items like "I am the life of the party", etc. As such, every factor score is a unique variable that probably doesn't ...

In attitude psychology Likert response scales are still the norm. They do have their problems (and there are a good deal of problems), but many of them can be addressed satisfactorily. The acquiescence bias you mention is a small issue. It can be balanced out by reverse coding roughly half of your test items. The acquiescence bias then becomes random noise ...

To clear this up, there is a distinction between phase difference and phase synchronization. Phase synchronization = is the phase difference constant with time? One crude way to measure phase synchronization would be to partition long signals $x(t)$ and $y(t)$ into many disjoint windows, compute the phase difference in each window using either Method 1 or ...

Methods 1 and 2 are matematically equivalent, but I have experienced that method 2 is computationally more efficient for high sampling rates and large ranges of delay (notice that method 2 does not require a loop).
